The results are totally unscientific, but they're kind of fun to look at. The Pajamas Media online poll may be indicative of little other than which candidates are generating a bit of excitement (and as the website indicates, who is able to "cheat" in the voting and spam votes for a particular candidate).
Keep in mind that when you vote in this poll (weekly) you don't have to pick only one party to vote in--so Republicans can vote for the one Democratic candidate they like (or would like to run against), as well as their favorite Republican candidate, and Democrats can do likewise.
Bill Richardson has been pretty consistently at the top of the poll for a number of weeks, which has no basis for believability in the "real" polls. Second and third place on the Democratic side are Barack Obama (trailing Richardson by about 30 points) and Wesley Clark, who hasn't announced. Clinton Gore, Biden and Edwards are all coming in with less that 7% of the vote, with Mike Gravel, the 70 some year old former Senator from Alaska coming in 4th, right behind Clark.
More interesting, I think, are this week's results on the Republican side. For a number of weeks, Rudy Giuliani led the pack by a significant margin, but he falls significantly this week, down to less than 13%, and Fred Thompson jumps to the top of the Republican list with 35% of the vote, followed closely by (who'd have thought) Ron Paul with 28.8%.
The Republican movement for Thompson and Paul, I suspect, has something to do with the fact that while a lot of people kind of liked Giuliani and McCain, and even Romney, they really aren't thrilled with the choices that they've got. Giuliani, likewise, may have some hurdles in the party. Some of those hurdles are the same that Ron Paul would have as a libertarian, although he has a bit more subdued persona, I think--and he probably doesn't really stand a chance of winning, anyhow, and his up-tick in the poll may have something to do with sort of a libertarian streak that runs through the internet community. Thompson's emergence as a leader in this poll, I think, suggests that Republicans are still searching.
