Reuters reports Donald Trump may be reaching the so-called "lost voters." These are often the same sort of individuals who were once called "Reagan Democrats."
Following the 2012 election it was reported that a large number of white blue collar voters, particularly in the rust belt states of MI, PA and OH simply stayed home. They didn't vote for Romney who, as a smooth uber-capitalist, wasn't especially popular with this demographic.
Trump appears to speak the language of these voters, they like his emotive style. The key question is whether, when November rolls around, they can be bothered to vote this time. They tell Reuters they will pull the lever for Trump.
