The alt-right, or alternative right, is a loosely defined group of people with far-right ideologies who reject mainstream conservatism in favor of white nationalism.
 White supremacist Richard Spencer initially promoted the term in 2010 in reference to a movement centered on white nationalism, and did so according to the "Associated Press" to disguise overt racism, white supremacism, neo-fascism, and neo-Nazism.
 The term drew considerable media attention and controversy during and after the 2016 US presidential election.
The inverse gambler's fallacy, named by philosopher Ian Hacking, is a formal fallacy of Bayesian inference which is an inverse of the better known gambler's fallacy.
 It is the fallacy of concluding, on the basis of an unlikely outcome of a random process, that the process is likely to have occurred many times before.
 For example, if one observes a pair of fair dice being rolled and turning up double sixes, it is wrong to suppose that this lends any support to the hypothesis that the dice have been rolled many times before.
 We can see this from the Bayesian update rule: letting "U" denote the unlikely outcome of the random process and "M" the proposition that the process has occurred many times before, we have

 He describes himself as "new right" and an "American nationalist".
 Cernovich's website "Danger & Play" started in 2012 and was originally known mainly for its content on men's empowerment.

Veterans for Bernie Sanders (also known as Vets for Bernie) was the first ever national grassroots association of military veterans to organize on behalf of a Presidential candidate, namely Bernie Sanders during the Bernie Sanders presidential campaign, 2016.
 Vets for Bernie, independent from the official campaign and largely organized via social media, grew to more than 50,000 military members, and over 100,000 followers on Facebook, Twitter, and Instagram.
 Founded by veterans of the Iraq war and Afghanistan war, Vets for Bernie became a key organizing force for progressives and military voters during the 2016 US Presidential campaign.

The United States presidential election of 1964 was the 45th quadrennial presidential election.
 It was held on Tuesday, November 3, 1964.
 Democratic candidate and incumbent President Lyndon B. Johnson had come to office less than a year earlier following the assassination of his predecessor John F. Kennedy.
 Johnson, who had successfully associated himself with Kennedy’s popularity, won 61.1% of the popular vote, the highest win by a candidate since James Monroe’s re-election in 1820.
 It was the most lopsided US presidential election in terms of popular votes, and the tenth-most lopsided presidential election in the history of the United States in terms of electoral votes.
 No candidate for president since has equalled or surpassed Johnson’s percentage of the popular vote, and since 1820, only Abraham Lincoln in 1864, Franklin D. Roosevelt in 1936, Richard Nixon in 1972 and Ronald Reagan in 1980 and 1984 have won by a greater electoral vote margin.
The 2016 Minneapolis shooting took place on June 29, 2016 in Minneapolis, Minnesota when a man named Anthony Sawina shot at five Somali-Americans, wounding two of them.
 Witnesses later recounted that Sawina shouted anti-Muslim expletives and claimed he was "going to kill [them] all."
 The attack was condemned by civil rights groups as part of a larger rise of Islamophobia in the United States leading up the 2016 presidential election.
