# Elezioni parlamentari negli Stati Uniti d'America del 2014

Le elezioni del 2014 negli Stati Uniti si svolsero martedì 4 novembre 2014, a metà del secondo mandato del presidente democratico Barack Obama. I repubblicani mantennero il controllo della Camera dei rappresentanti e ottennero il controllo del Senato.
I repubblicani conquistarono nove seggi al Senato, il più grande guadagno al Senato per uno dei due partiti dal 1980. Alla Camera, i repubblicani conquistarono tredici seggi, ottenendo la maggioranza più ampia per il partito dell'elefante dall'inizio della Grande Depressione. Durante l'anno si svolsero varie altre elezioni e referendum statali, territoriali e locali. L'elezione fu comunemente citata come una "valanga repubblicana"
Con una spesa totale per la campagna elettorale che raggiunse $ 3,7 miliardi, le elezioni di metà mandato, all'epoca, furono le più costose della storia, e vennero poi superate dalle elezioni di metà mandato del 2018 quattro anni dopo. Le elezioni del 2014 videro anche l'affluenza alle urne più bassa dal 1942, con appena il 36,4% degli aventi diritto al voto.
La maggioranza del Senato repubblicano ottenuta in queste elezioni consentì ai repubblicani di nominare tre giudici della Corte Suprema negli anni successivi.
I temi principali delle elezioni riguardarono la disuguaglianza di reddito e il Patient Protection and Affordable Care Act (comunemente denominato "Obamacare"), che i repubblicani cercavano di abrogare. I democratici promossero la loro proposta per aumentare il salario minimo. Nelle settimane precedenti le elezioni del 2014, i repubblicani criticarono aspramente l'amministrazione Obama per la gestione dell'epidemia del virus ebola del 2013-2016 in Africa occidentale. Tuttavia, subito dopo le elezioni, i repubblicani smisero di parlare di ebola. Studi del 2016 e del 2020 rilevarono in seguito che la retorica repubblicana sull'Ebola potrebbe aver aiutato i candidati repubblicani alle elezioni del 2014.
Sebbene abbia suscitato molto dibattito all'inizio del 2014, il Keystone Pipeline alla fine ricevette poca attenzione nelle elezioni, con gli ambientalisti invece concentrati sulla lotta al riscaldamento globale e sul sostegno dei regolamenti proposti dall'EPA sulle emissioni di gas serra. Un'altra questione potenzialmente importante, la neutralità della rete, ottenne poca attenzione durante la campagna.
I sondaggi di uscita nazionali mostrarono che per il 45% degli elettori l'economia era la questione più importante, in calo rispetto al 2010 e al 2008 (quando rispettivamente il 59% degli elettori e il 63% degli elettori lo avevano indicato come il problema principale), ma era ancora il problema più comune citato dagli elettori come più importante per loro. Un numero minore di elettori indicò l'assistenza sanitaria, la politica estera o l'immigrazione illegale, o il matrimonio tra persone dello stesso sesso, l'Ebola o la legalizzazione della marijuana come i problemi principali.
Con un totale finale di 247 seggi (56,78%) alla Camera e 54 seggi al Senato, i repubblicani alla fine raggiunsero la maggioranza più ampia al Congresso degli Stati Uniti dal 71º Congresso nel 1929.

## Senato

Tutti i 33 seggi della Classe II del Senato erano in attesa di rinnovo. Inoltre, si tennero tre elezioni speciali per coprire i seggi vacanti nella Classe III.
Sui 36 confronti per il Senato, il Partito Repubblicano ne vinse 24 (per un guadagno netto di nove seggi, che rappresentò il più grande guadagno per un partito al Senato dal 1980 e il più grande guadagno al Senato a metà mandato dal 1958) e il Partito Democratico ne vinse 12, portando così i repubblicani a riprendere il controllo del Senato per la prima volta dal 2006, con un totale di 54 seggi. La gara in Louisiana si diresse al ballottaggio il 6 dicembre 2014, in cui la Repubblicana Bill Cassidy (R) sconfisse il senatore in carica per 3 mandati, Mary Landrieu, con il 55,9% contro il 44,1%.

Si svolsero anche le elezioni per selezionare i delegati per il Distretto di Columbia e quattro dei cinque territori degli Stati Uniti. L'unico seggio alla Camera non candidato alle elezioni era il Commissario residente di Porto Rico, che ha un mandato di quattro anni. Il Partito Repubblicano conquistò 247 seggi (per un guadagno netto di 13 seggi) e il Partito Democratico, 188 seggi. I repubblicani ottennero così la maggioranza più ampia alla Camera dal 1928. A livello nazionale, i repubblicani vinsero il voto popolare per la Camera dei rappresentanti con un margine del 5,7%.
L'11 marzo si svolse un'elezione speciale per il 13º distretto congressuale della Florida, vinta dal Partito Repubblicano.

## Affluenza

L'affluenza alle urne a livello nazionale è stata del 36,4%, in calo dal 40,9% delle precedenti elezioni di metà mandato del 2010 e la più bassa dalle elezioni del 1942, quando solo il 33,9% degli elettori si era presentato, sebbene quell'elezione fosse avvenuta durante la seconda guerra mondiale.
Gli stati con la più alta affluenza alle urne sono stati Maine (59,3%), Wisconsin (56,9%), Alaska (55,3%), Colorado (53%), Oregon (52,7%) Minnesota (51,3%), Iowa (50,6%), New Hampshire (48,8%), Montana (46,1%) e Dakota del Sud (44,6%). Tutti questi, con l'eccezione di Iowa e Montana, presentavano una competizione contendibile per la carica di governatore e tutti tranne Maine e Wisconsin avevano anche competizioni contendibili al Senato. Gli stati con la più alta affluenza alle urne che non avevano una competizione contendibile al Senato o alla carica di governatore dello Stato nel 2014 furono il Dakota del Nord (44,1%) e lo stato di Washington (38,6%).
Gli stati con l'affluenza più bassa sono stati Indiana (28%), Texas (28,5%), Utah (28,8%), Tennessee (29,1%), New York (29,5%), Mississippi (29,7%), Oklahoma (29,8%), New Jersey (30,4%) e West Virginia e Nevada (31,8%). Indiana e Utah non avevano elezioni per il Senato o il governo e gli altri avevano tutti elezioni per almeno una delle cariche, ma non erano considerati contendibili. L'affluenza alle urne a Washington, DC è stata del 30,3%.
Secondo la CNN, i giovani americani di età compresa tra i 18 ei 29 anni rappresentavano il 13% dell'elettorato, in calo rispetto al 19% delle elezioni presidenziali di due anni prima.
L'analisi del Pew Research Center ha rilevato che il 35% dei non votanti ha citato impegni di lavoro o scolastici, che hanno impedito loro di votare, il 34% ha affermato di essere troppo occupato, malato, lontano da casa o ha dimenticato di votare, il 20% non lo ha fatto come scelta consapevole, non ne sapeva abbastanza o non gli importava e il 10% si era trasferito di recente, non si era registrato in tempo o non aveva mezzi di trasporto.
Il New York Times considerò l'apatia, la rabbia e la frustrazione per il tono inesorabilmente negativo delle campagne come ragioni della bassa affluenza alle urne e affermò: "Nessuna delle parti ha fornito agli elettori una ragione affermativa per presentarsi alle urne".

## Polemiche e altri problemi
### Accuse di cattiva condotta

La rappresentante dello Stato del Connecticut Christina Ayala (democratica) è stata arrestata nel settembre 2014 con l'accusa di frode elettorale, in particolare "otto conteggi di voto fraudolento, 10 conteggi di violazioni primarie o di iscrizione e un conteggio di manomissione o fabbricazione di prove fisiche". Nel settembre 2015 si è dichiarata colpevole di violazioni delle leggi elettorali statali, ha ricevuto una condanna a un anno (sospesa) insieme a due anni di "congedo condizionale" e ha accettato di non candidarsi a cariche elettive per due anni. Anche sua madre, il cancelliere democratico degli elettori di Santa Ayala, è stata oggetto di un'indagine nel caso, ma non è stata accusata.
Il senatore dello stato della California Roderick Wright (democratico) si è dimesso dall'incarico nel settembre 2014 ed è stato condannato a 90 giorni nel carcere della contea di Los Angeles per falsa testimonianza e frode elettorale. Nonostante fosse stato condannato mesi prima per 8 reati, Wright è stato autorizzato a prendere un congedo retribuito come senatore di stato.
A Chicago, i giudici elettorali hanno affermato di aver ricevuto telefonate automatizzate tra ottobre e novembre con istruzioni apparentemente false sul voto o sulla formazione richiesta, secondo il Chicago Sun-Times. A Pontiac, nel Michigan, i Democratici locali hanno citato rapporti di molestie e intimidazioni nei confronti degli elettori da parte dei repubblicani per aver messo in discussione le schede elettorali legalmente espresse con i lavoratori elettorali che hanno ripetutamente dovuto chiedere loro di farsi da parte. Un impiegato ha chiamato la polizia per chiedere aiuto.

### Nuove restrizioni di voto

Nel giugno 2013, la Corte Suprema ha invalidato parte del Voting Rights Act del 1965, consentendo a nove stati (per lo più meridionali) di modificare le proprie leggi elettorali senza previa approvazione federale. Dal 2010, 22 stati hanno emanato nuove restrizioni di voto. Le elezioni federali del 2014 sono state le prime elezioni federali in cui 15 stati hanno emanato nuove restrizioni di voto, molti dei quali hanno dovuto affrontare sfide in tribunale.

### Problemi con la macchina per il voto

Si sono verificati problemi sparsi con le macchine per il voto, con macchine calibrate in modo errato che hanno registrato un voto espresso per un candidato come voto per un altro candidato. Si sono verificati in Virginia, Maryland, Illinois, e North Carolina.
Nella contea di Bexar, in Texas, il candidato repubblicano alla carica di governatore, Greg Abbott, è stato accidentalmente sostituito al ballottaggio da David Dewhurst su una macchina, su cui sono stati espressi 12 voti prima che il problema venisse rilevato.
