It's pretty amazing to consider that there is (according to the polls, at least) some small but non-zero percentage of voters who are, after a couple of years or so of campaigning, still undecided about whom they will vote for in the presidential election. I suspect that there aren't a huge number of undecideds among VC readers, who are a pretty opinionated and politically-active bunch. But I'd be curious to hear from anyone who is in that category today. Did any of you actually head to the polls this morning not knowing for whom you'd vote for president? What did you ultimately decide? And why?
