He gained one since yesterday, as both Gallup and Rasmussen show Obama opening up a small lead in recent days.

The details…:

McCain’s percentage of the vote has been remarkably steady of late, varying only two percentage points, between 42% and 44%, for over two weeks. In fact, McCain has received precisely 43% of the vote in each of the last four Gallup tracking reports. Obama’s percentage of the vote has varied slightly more, but has generally been at 46%, 47%, or 48% for weeks. A focus on the “gap” between the two candidates can overemphasize change, but even the more volatile trend in the margin doesn’t reflect much change in the nature of the race.
