Republican insiders believe that any candidate who is labeled as pro-amnesty will not win the 2016 nomination, conceding how strongly GOP primary voters are opposed to illegal immigration and amnesty for illegal immigrants.

After surveying political insiders from the early primary states, Politico noted that “many insiders argue that anyone who is perceived as supporting amnesty can’t win.” Other insiders reportedly noted, though, that “there are very few candidates who have been totally pure on the issue.”

In New Hampshire, for instance, a Saint Anselm College poll recently found that 41% of GOP primary voters view Jeb Bush’s pro-amnesty immigration stance as a “deal-killer.” Wisconsin Gov. Scott Walker, who has been leading in some New Hampshire and Iowa polls, will also have to answer for his past support for the McCain-Kennedy comprehensive amnesty bill and a pathway to citizenship for illegal immigrants
