Democrat Stan Greenberg and Republican Glen Bolger conducted the first public battleground poll of this election cycle. They chose the 70 House districts experts regard as most likely to oust incumbents this fall. What they found was grim news for Democrats.
For this poll, Bolger and Greenberg chose the districts where incumbents are considered the most vulnerable, and, in the case of open seats, the ones most likely to switch party control in November. Sixty are currently held by Democrats — many of whom won these seats even when voters in the same district preferred Republican John McCain for president in 2008. The other 10 districts are the flip side — held by Republicans in the House, even though their voters went for Barack Obama in 2008.
These are this year's swing seats — the political terrain where the battle for control of the House of Representatives will be won or lost. In this battleground, voters are choosing Republicans over Democrats 49 percent to 41 percent.
