"In every town large enough to have two traffic lights there is a bar at the back of which sits the local Donald Trump, nursing his fifth beer and innumerable delusions. Because the actual Donald Trump is wealthy, he can turn himself into an unprecedentedly and incorrigibly vulgar presidential candidate. It is his right to use his riches as he pleases. His squalid performance and its coarsening of civic life are costs of freedom that an open society must be prepared to pay."
I think Trump supporters are versions of the semi-drunk delusional bar fly described by Will, and those who delight in the silliness of right wing talk radio and FOX News, whose main message seem to be that all we need to do is get a president and congress who are really, really, really, really, really, really, really, really, really, really. really, really, really, really ... and I mean really ... TOUGH.
And what about the polls? At this point in the campaigns they are little more than name recognition. Its very predictable that the biggest winners of today's polls are simply the most famous people - Clinton, Bush, and Trump. Saying you like someone today doesn't mean you are going to vote for them when the time comes.
