Is Hillary a real person? Sure. Everybody's a real person. Is she the kind of person I'd want to support for President of the USofA? Not really, but if she ever comes out with some concrete policy positions, I just might feel better or worse about her. Right now, I'm with Bill DeBlasio, waiting to see if she might (ahem) "clarify" what she's thinking. Her history would have me believe she's more hawkish than I can accept, and a bit more in the pocket of Wall Street than I'd like. Needless to say, whatever positions she takes for the campaign will not bind her to any particular positions she takes as president, but that's true of anybody in politics.
While it would be nice if Ted Cruz managed to win the Republican nomination since that would more or less guarantee a Democratic victory next year, I'd much prefer somebody who might push Hillary further left. Given the yahoos who form the Republican base, Rand Paul doesn't seem to have much of a chance, but given his foreign policy positions, I might even consider voting for him over Hillary (or the third-party candidate I usually wind up supporting here in dependably Democratic New York.) Tell me though: what is libertarian about opposing abortion and same-sex marriage? And if, by some miracle, he ended up our next president, would he follow through? Politics as usual.
If the Republican base had any brains, it would nominate Marco Rubio. He's good looking, articulate, and smart. Granted, I don't much care for his positions on, well, anything, but if the GOP is looking for a winner, I think he'd be a better bet than Jeb Bush.
