With Clark rising in the polls, Dean is back to accusing Wes Clark of being a Republican.

According to Reuters, today he said that he thought Clark was a "good guy, but I truly believe he's a Republican ... I do not think somebody ought to run in the Democratic primary and then make the general election a Republican primary between two Republicans."

If Clark is a Republican, why did he vote for the Democratic presidential ticket in 1992, 1996 and 2000?

If the issue is Reagan or Nixon, those two won pretty handily (at least for reelection). To win, any Democrat will need lots of Democrats who pulled the lever for them too.
