Judicial Watch has been anti-Bush since the fall of last year.
They aligned themselves with Gore in the Florida courts trying to get a recount to overturn the election results.
They have filed ethics complaints against Cheney, DeLay, the RNC, Haskert, and other conservatives. All were frivilous.
They have never won a case. Most of their cases get thrown out of court before trial. In fact, I can't think of any case they have even been able to get to trial.
