Obama ahead in Bucks County

Politico has a story today on how Sen. Barack Obama holds leads in four key counties that will help him win swing states -- including a sizable lead in Bucks County.

Here's the paragraph on Bucks:

In Bucks County, a politically competitive but historically Republican suburb that shares a border with Philadelphia, Obama is running ahead of McCain, 47-41 percent. In 2004, Democrat John F. Kerry carried the county by a slim 51 percent to 48 percent.
