Of all the members of the House Republican caucus, the guy who seems to have heard from the most TPM readers (or at least high on the list) is Greg Walden of Oregon.
Oregonians who called, but weren't from Walden's district, apparently got a bit of a tongue-lashing. But those who were his constituents got either a 'we don't know how he voted' or some version of 'the person who answers that question is away from their desk', etc. Pretty much all of Walden's constituents got the run-around and none of them got a straight answer. Lots of them got promises of calls back. But nobody seems to have gotten one.
There was apparently at least one rather hard-boiled staffer in one of the Walden offices, though. Because, in at least two cases, callers were told that in the staffer's opinion Walden almost certainly gave DeLay the nod.
