Mitt Romney has now moved into a tiny lead in Ohio, the first time since early this evening. But here’s another thing to watch. In Ohio, a candidate has to win by more than .25% of the vote to avoid a mandatory recount. In practice that means the victory has to be more than about 2,000 votes. That’s just about where Romney is right now.

So there’s who has the most votes tonight but there’s also the margin the candidate needs to avoid a mandatory recount.
