Public Policy Polling (5/15-16, likely voters, 4/17-18 in parens):
Mark Critz (D): 47 (41)
Tim Burns (R): 48 (44)
Undecided: 6 (15)
(MoE: ±3.4%)
More, from Jensen:
If Burns does pull out the victory on Tuesday night it will be more because of a continuing gap in interest between Democratic and Republican voters in the off year election than anything else. Critz is actually winning over more McCain voters (14%) than Burns is Obama voters (12%). This race is not an example of people who voted for Obama who are now unhappy with him and voting Republican. But those planning to vote on Tuesday report having voted for John McCain by 5 points in 2008, compared to his actual 1 point victory in the district. And among voters who say they're 'very excited' to vote in this election, Burns has a 60-38 lead.
Two recent polls have given Critz a slight lead. It looks like we're heading for a photo finish here, sports fans.
