With the exception of the NYS Comptroller's race, I'll be voting for Democrats across the board tomorrow. In that particular race, I'll be voting Green since the incumbent Democrat is a crook. (I may actually vote Green for Governor as well, seeing as how Elliot Spitzer can't possibly lose but the Green Party would benefit from getting as many votes as it can, but I won't make that decision until I'm standing in the booth.)
Lots of people say that voting a straight party ticket is bad, but I don't really see that, except in extreme cases (if there wasn't a Green candidate for Comptroller, I'd probably abstain). When confronted with an incompetent Democrat versus a competent Republican, I either abstain or vote for the nearest convenient liberal party, and for me, I don't think my interests are served if I help elect someone whose stands on the issues don't mirror mine. So for me, primary day is the time to exercise my distaste for incumbency.
And besides, I'm generally of the view that the national Republican Party is a cesspool, and my antipathy towards them extends downward, since today's local Republicans are tomorrow's national Republicans. So it's all Democrats for me. I don't put a whole lot of stock in independence as a voter. I'm a Democrat because there are certain things I believe and certain things I value and certain things I want my country to do and to be, and I cast my votes accordingly, and with the full knowledge that I'll never get everything I want, because nobody ever does.
