No he did not. He voted with democrats to KILL a Bush Impeachment Resolution.
Most Republicans voted against killing the bill, because they wanted to debate it and vote on the bill. They were pretty sure they would win the vote on the bill, so their votes were also against impeachment, but only indirectly.
The more direct anti-impeachment vote was to kill the bill. Although most of the democrats voted to kill the bill to save themselves the embarrassment of losing the vote on the floor.
BTW, this isn't the only time in history this has happened -- it actually happens quite often. If the minority thinks they have enough votes to kill something Pelosi wants, they vote to bring it to a vote, and the democrats have a vote to take the bill off the floor. Although normally pelosi just pulls it off the calendar -- they couldn't pull this one, because Kucinich used a privileged resolution which has to be disposed of by a vote.
That the democrats threw it into the big freeze due to it being a lost cause is not the same as killing the bill, semantics. To vote for and justity the freeze rather than taking it to the floor with the very strong likelyhood of winning was a hedge that is now coming back to haunt him.
