A lot of national polls have come out lately with few polls done in the primary states that really matter.

Here’s a recent one in Iowa that shows Edwards maintaining his lead and the Hillary momentum possibly less than some thought:

John Edwards 24%
Hillary Clinton 18%
Barack Obama 18%
Tom Vilsack 14%
Joe Biden 5%
Bill Richardson 3%
Wesley Clark 2%
Chris Dodd 1%
Dennis Kucinich 1%
Undecided 14%

Polls are obviously way early, but if he is holding his lead there even after the announcements and visits by Obama and Hillary, its a pretty good sign for the Edwards campaign.
