Its early and Trump may eventually get a lot of democrats to switch parties but unfortunately polling shows problems with that hope.
"A March Washington Post poll found that in a hypothetical matchup with Trump, Hillary Clinton wins Democrats 86 to 9 percent. That means, right now, that Trump does indeed gain a few more Democratic defections than Romney did. The problem is that Trump is only winning Republicans 75 to 14 percent. In other words, more Republicans are planning to vote for Hillary than Democrats are planning to vote for Trump, which helps explain why Clinton is leading in almost all the head-to-head polls."

A lot of folks are NOT crazy for Hillary either, even more so.
