From Jake Tapper’s Political Punch:

The 52 members of the House Blue Dog Caucus of moderate to conservative Democrats are, like most other members of Congress, back in their home districts.
Members of this group — targeted by House Democratic leadership, the White House, and special interest groups — has largely been non-committal in public statements about whether or not they will vote for the health care reform legislation that ends of up on the floor of the House.
But despite efforts by Congressional leaders and the White House to make the legislation more palatable to them — by, perhaps, eliminating, the public health care option, or imposing more Medicare cuts — many of these members of Congress have sounded more skeptical of the bill as of late, according to local media reports.
