He's given me no reason to vote FOR him outside of what he has done to turn the Ruling Class Establishment on it's head and he's self-funding his campaign so he has skin in the game.
Outside of that, He's given me nothing concrete outside of his bombast to look at and analyze as viable.
Yes, he brought the illegal invasion to the fore of attention. Great. His plan to deal with it makes a nice slogan and appeals to base instincts, but I have to hear or see how any of that will be done in any realistic fashion. When questioned on specifics Trump gets agitated and simply repeats that he will build it bigger, without any specifics on how he is going to do that.
His rabid followers on the other hand, have given me every reason I now oppose him, and strangely for similar reasons I opposed Ron Paul and Obama in 2008.
Trump's an opportunist, riding a wave of long-simmering anger to propel his campaign. Slogans and appeals to base instincts are the tools for that.
