The Orange County seat held by  Rohrabacher  is key to Democratsâ hopes to increase their numbers in the U.S. House of Representatives in next yearâs elections. Neuroscientist Hans Keirstead  a stem cell researcher and entrepreneur from Laguna Beach  is one of seven Democrats aiming to beat him  according to the Federal Election Commission.
 Rohrabacher   a senior member of the House Committee on Foreign Affairs  has frequently praised Russian President Vladimir Putin and was considered for a role in U.S. President Donald Trumpâs cabinet.

SOLUTION: Dana Rohrabacher

PROBLEM: The primes are "suspicious  solitary numbers " Giordano writes. Perhaps they would prefer to be ordinary numbers  "but for some reason they couldn't do it." And he elaborates: There are some that almost touch -- 17 and 19  41 and 43 -- but are separated by an even number. As the numbers expand  these so-called twin primes become ever rarer  and the presentiment develops that these were accidents  and "that solitude is the true destiny." But then  if you count long enough  you'll find another pair of twins  "clutching each other tightly." Giordano depicts with aching vividness the traumas out of which Alice and Mattia emerge disabled. Alice's ski fall might be only that  despite a permanently crippled leg. But we get horror seen from within: a father who bullies her  even if lovingly  into enduring the cold  the awkwardness  the fear of something she has so little taste for that she humiliatingly befouls her ski pants. Adults cannot suspect what furnishes a child's nightmare; here  the reader is made to live it.
 Giordano remarkably and movingly portrays the hesitant groping toward warmth that works beneath the pair's emotional disabilities. Alice  unable to tolerate not just food but also the vitality it stands for  assumes a touchingly decisive if frail seductiveness with the shaky Mattia. When at 22 he brings himself to tell her about his sister  she embraces him  they kiss  and for a moment it seems things will change.
 Only briefly; Mattia retreats  goes off to Scandinavia. Upon his return years later there is another almost-moment. That too will vanish. Alice's reaching out  though tentative  is genuine. His response describes a parabola: rising  seeming to converge  dropping away. He is the man who fell to earth; she is earth  though crumbly.
 What is even more distinctive  and transforming  is the writing. The author works with piercing subtlety. He manages -- moving from math to physics -- an exquisite rendering of what one might call feelings at the subatomic level  emotion's muons  gluons and quarks. Take that kiss: "All Mattia saw was a shadow moving toward him. He instinctively closed his eyes and then felt Alice's hot mouth on his  her tears on his cheek  or maybe they weren't hers  and finally her hands  so light  holding his head still and catching all his thoughts and imprisoning them there  in the space that no longer existed between them."

SOLUTION: Alice

PROBLEM: She entered the public eye in July 2014 when her father   Eric Garner   died after being put in a chokehold by a New York City police officer.  Eric Garner  was seen on video saying  "I can't breathe" 11 times before  he  died.
A grand jury did not indict any officers in  Eric Garner's  death  sparking more protests across the country. The coroner's report lists  his  death as a homicide  but no officer has ever been charged in the case. In 2015  the city of New York settled with his family for $5.9 million.
In the Sanders video   Garner  explained why she became an activist.
"I'm just trying to get the truth out there to tell  his  side of the story " she said of her late father. "He was being a loving  caring man that he was  and he was murdered. For a whole year  I've protested every Tuesday and Thursday. I feel like a representative for people throughout this whole nation because I'm doing this  I'm speaking out  me being his daughter. And that's what I want to do  I just want to tell my truths."

SOLUTION:
Eric Garner
