Donald Trump opened his White House bid by stoking fears of Mexicans flooding the border. But in the end, it may be a Latino voter surge that walls him out.

In states crucial to Trump's win, Hispanics have had an outsized presence at the polls, waiting out long lines in Florida, Nevada, Arizona, North Carolina and other states.

In the crucial battleground state of Florida, 565,000 Latinos had voted early, in person, a 100 percent increase over 2012, the Miami Herald reported. The total rises to 911,000 with absentee ballots.

More important, more than one third of those early votes in the Sunshine State were cast by Latinos who had not voted in 2012. The turnout appears to favor Clinton, with high turnout rates in Democratic counties.

The best visual evidence of a potential Latino surge came last week when early voting hours had to be extended in Nevada because so many people, largely Latinos, were in line at Cardenas grocery store in Las Vegas.

This led Nevada political analyst Jon Ralston, an expert in the state's politics, to warn the GOP in a tweet that it was time to panic and to give his own twist to Trump's opening salvo on Mexicans. "They're bringing drugs. They're bringing crime. They're rapists. And some, I assume, will stop me from being president." - NBC News
