There’s still no chance Obama will lose here, but this is another good example of a surging Romney campaign.

Via Boston Globe:

[B]rown, a Republican in an overwhelmingly Democratic state, may also be benefiting from a slight uptick in support for Republican presidential nominee Mitt Romney among Massachusetts voters. The poll shows that Obama leads Romney 52 percent to 38 percent, a substantial margin, but down significantly from last month, when Obama held a 27 point lead over Romney in Massachusetts.

That finding suggests Obama’s thinner lead could be having a spillover effect in the Senate race, because even a small trim in his margin of victory would make things easier for Brown, who needs support from hundreds of thousands of Obama voters to defeat Warren, a Democrat.

If the gap at the top of the ticket is indeed shrinking, that would be good news for Brown. He has had some success with Obama voters, but they still support Warren in overwhelming numbers. Brown drew 12 percent of likely Obama voters, compared with 73 percent for Warren.

The poll of 583 likely voters was conducted from Wednesday through Sunday by the University of New Hampshire Survey Center.
