House passes resolution condemning MoveOn's "Betray Us" ad

Sixteen days after the ad appeared in the Times, the final chapter to this travesty is written. The vote was 341-79; here’s the roll if you’re curious to see how it shook out. Italics denote Republicans, roman typeface denotes Democrats. What do the 79 nays have in common?

Your quote of the day from David “Idiot Liberals” Obey, who may be a jerk but very occasionally is my kind of jerk:

Wisconsin Rep. David Obey, a veteran Democrat, recounted how he left the Republican Party during the era of Sen. Joseph McCarthy, R-Wis., and said that lawmakers have an obligation to criticize their allies as well as their enemies when they go too far.

“I’ve got an obligation to be equally upset when that kind of juvenile debate emanates from the left,” Obey said.

Exit question: 341 + 79 + 12 not voting = 432, not 435. Why aren’t the other three members accounted for? Pelosi isn’t listed at all, presumably because the Speaker typically doesn’t vote, but why not just stick her in the NV column then?
