2. Romney’s made gains where it matters on the map
In The Washington Post’s tossup states of Nevada, Colorado, Iowa, Wisconsin, Florida Virginia and New Hampshire (plus Ohio, which leans toward Obama, but isn’t out of Romney’s reach), Romney’s at 52 percent while Obama’s at 46 percent. Given the sample size, it’s not a significant edge for the Republican, but still represents a reversal from where the race has stood in those battlegrounds up until now. It’s worth noting, too, that both Romney and Obama are attracting about 60 percent support in the states that lean toward them or are solidly in their corner.
-- WTF does the "small sample size" mean?
