Perhaps the โ€œHouse Democrat logicโ€ that eludes me below rests on the supposition that constituents are stupid and will believe anything you tell them. Stacy, a constituent of John Barrow, Georgia Democrat, shares this less-than-edifying discussion with a staffer:

Just got off the phone with a Barrow lackey. He tried to convince me that Barrow wants an up or down vote on the health care bill and blamed the Republicans for forcing Barrow to vote against requiring an up or down vote on the health care bill. I have been told for days and days that he is reading the bill. They will not tell us how he will vote on the health care bill or even how he will vote on the rule regarding the self execution of the bill. Is he reading that too?
He also told me that no matter what is in the Senate bill, the Hyde Bill will prevent federal funds from being used for abortions. So I asked what all the fuss was about then. He told me the fuss is once again because of the Republicans. I asked him if Stupak was a Republican. Then he rambled off a bunch more nonsense about Republicans and threw in a few lies about the Bush tax cuts โ€“ HUH?!?
I was asked if I had a message for my Congressman. I told them to tell Barrow that we arenโ€™t as stupid as the people answering the phones want to believe we are.

Barrowโ€™s position, apparently, is that he wants an up-or-down vote on the health-care bill, so he voted for a resolution that ensures there will be no up-or-down vote on the health-care bill.

UPDATE: From another reader in Georgia, living in the other district represented by a vulnerable Democrat:

I called Jim Marshall (D-GA), my former congressman before I moved a few miles outside the district. I was assured by the guy answering the phone that he is a definite no. But then I asked, OK then why did he vote for the Slaughter rule? The guy mumbled something about procedure to pass. I think he was just a guy reading off a script and so I didnโ€™t want to get into it with him, whatโ€™s the point. But he did say 3 or 4 times that Jim Marshall is a no. FWIW.
John Barrow sounds like a definite cave.

To be fair, just about every count Iโ€™ve seen has considered Marshall a likely โ€œno.โ€
