The Blue Dogs were only holding up the process because of cost and how quickly the agenda was proceeding. I don’t recall them having concerns over content or government control. Also, they reached agreement, apparently, before the August recess. I’m not sure how much in “play” they are, unless they took their constituent’s concerns to heart. I’m not holding my breath.
They're looking at polls, and growing discontent. I'm not holding my breath, either, since it's still a matter of the stronger influence -- threats that they will be dumped by Emanuel (who basically controls the DNC purse strings), or whether they can swim on their own. Who the Republican competion is (if any), and whether they can maintain the seat without the support of the DNC are major factors. (And the DNC can always come up with an alternate liar in their place, come the primaries.)
