Trump: Best Way to Protect Sanctity of Life Is to Vote for Me

EXIT POLL: Almost Half of Sanders Voters in WV Say They'd Vote Trump in General

Tonight's results in West Virginia are a far cry from 2008. Back then, Hillary Clinton beat Barack Obama by a whopping 41-point margin.

That was not the case tonight, as she lost to Democratic socialist Sen. Bernie Sanders by 10 percent, with two-thirds of precincts reporting.

"This night, in more than one respect, is all about her weakness as a candidate," Brit Hume said on The Kelly File. "Her surprising weakness, despite the odds now in her favor among Democrats."

He said that new polling out today in the major battleground states of Pennsylvania, Ohio and Florida "suggests that she is far weaker as a general election candidate in those key states than one might have imagined against Donald Trump."
