Today's Washington Post poll shows that Democrats "have made modest improvements," the paper reports. Actually, the improvements are pretty major. In the last poll, Republicans led by 2 points among registered voters and a staggering 13 points among likely voters. In today's poll, Democrats lead by 4 points among registered voters, and Republicans lead by 6 points among likely voters. That's a 6-7 point gain, which is actually pretty enormous.

Now, there's some reason to think the generic ballot may underestimate the Democratic share of the House vote. But generally speaking, the story is that the Democrats are rising, but from a very low starting point.
