We have many more, for two simple reasons:
1. FreeRepublic has a much larger membership.
2. Virtually all of the "facts mess up my agenda" subset are DU trolls.
Once they're zotted, or had the errors of their ways described in great detail to them, they scurry back to DU. Their common thread consists of extreme vulgarity with no common sense, and their hate for President Bush. These masturbatory threads then continue for 40-60 posts, until the next battle-weary DUmmy comes to detail his exploits at FreeRepublic.
I guess DU is the perfect place for the Deaniacs.
But it appears from looking at the membership dates on some of these "pessimists" that DU trolls have been here quite a while. Only now are they 'voicing' true conservative disagreement with GW's mistakes. Make no mistake, these liberals may be basically morally corrupt and have made a lot of mistakes about the basic morality of the American heartland, but they have also learned the clever art of subterfuge, disinformation, and feigned sincere questioning of the current policies. It is nothing more than intellectual espionage and PSY OPS against the Republican base. The ones here since after 2000 (there are a few) are revenge for Florida.
