Republican pollster Ed Goeas made the point yesterday that the American electorate is still closely divided. Democrats enjoyed a solid advantage in the national vote for U.S. House, of course, but some of that reflected large margins in already Democratic districts. In the battleground districts, the outcomes were determined by small margins in most cases. Goeas said that of the 28 House seats that (at the point he was talking) flipped to the Dems, 22 were won by less than 2 percent of the vote, 18 by 5,000 or fewer votes, and four by fewer than 1,000 votes.

It?s worth noting, however, that this kind of math works both ways. There were some Republican seats saved by a handful of votes, such as the 8th District here in North Carolina, where incumbent Rep. Robin Hayes appears to have won with fewer than 400 more votes than his underfinanced Democratic opponent, Larry Kissell.
