The Iowa caucus is tomorrow, and the Republicans continue to bash each other, although Mike Huckabee decided not to run a harsh attack ad, while liberal bloggers try to make sense of a recent Iowa poll, which was heavily influenced by independent voters. Will independents actually caucus Democratic in Iowa? I have my doubts. Republicans Jonathan Martin at politico.com blogs about Mitt Romney being a defender of President Bush. I could see Romney defending Reagan, but I don't really understand the alignment with Bush. Matt Lewis at townhall.com points out that Sen. John McCain (R., Ariz.) is better on foreign policy than Romney. Romney fixing the 2002 Winter Olympics in Utah fails to count for foreign policy experience. Jim Geraghty tries to figure out whether Mike Huckabee's campaign really made a last-minute decision to kill an attack ad on Mitt Romney in Iowa. Did Huckabee's campaign try to pull a fast one by cancelling an attack but then making it available to the media? Democrats Eriposte at leftcoaster.com discusses the recent Des Moines Register Poll. It is the only poll indicating a big lead by Senator Barack Obama (D., Ill.), and many call it the "gold standard" for polls there. Eriposte isn't convinced. John Hinderaker at powerline.com analyzes John Edwards' most recent commercial. He finds the ad effective but misleading. The real person behind the ad also happens to be a Democratic party activist. Hinderaker thinks that the party affiliation puts his working class designation into question. I'm not so sure.
