The day before the election, someone from moveon.org showed up at my door and asked me whether I meant to vote. I can't remember whether she asked who I meant to vote for.
Then she asked me when I intended to vote and said when I did vote, I should check in with one of their volunteers at the site and if I hadn't voted by an hour later, they'd check in with me to see whether I was ok.
As I'm typing this, it does seem rather intrusive, but at the time it didn't bother me since I had a strong intention to vote.
Afterwards, I mentioned it to various people, and no one else had run into the same thing--do people think this is a sensible way of trying to get out the vote, or would it just tend to annoy marginal voters?
