I looked on Pollingreport.com and saw that the
LA times latest poll on the congressional matchup was taken August 22-25. It showed Dems 47%, GOP 39%. But I think that was taken when Republicans were on vacation (and on a WEEKEND no less). This Washington Post poll was taken mid-week (Sept. 3-6) which I am told is more accurate if you're just going to take a poll of adults/registered voters.
