I don't support Rubio over a purely parochial issue.
I voted for Mel Martinez in 2004, so it's not because he's Hispanic. And, again: I'm a 2012 Obama voter, FWIW.
It makes no sense to vote for Trump and then the Democratic Senate candidate who will do everything to block the Trump agenda.
On the contrary. There are some people who intentionally vote this way with the intention of allowing neither party to have full control of government. I used to have some sympathy with this viewpoint because it forced the parties into some measure of consensus and compromise. However, since those have become dirty words to hard-line Republicans, all that mixed-party government accomplishes now is to prevent anything from getting done.
