A new Research 2000 poll conducted for KCCI in Iowa shows Edwards still leading with 27%, followed by Clinton at 22% and Obama at 16%. Also breaking double-digits, Bill Richardson at 11%. In May, Research 2000 had Clinton in the lead with 28%, followed by Edwards at 26% and Obama at 22%, with Richardson at 7%. So only Edwards and Richardson saw their numbers go up (though Edwards' inch up was statistically insignificant). Of significance, both Clinton and Obama went down.
On the GOP side, Romney has a double-digit lead. He sits at 25%, with Thompson at 14%, Giuliani at 13%, and McCain at 10%. This is a BIG change since May, when McCain, Giuliani, and Romney were all bunched up top at 18%, 17%, and 16%, respectively. Also of note in the poll, a majority of all Iowans favor impeachment proceedings against Cheney, including 63% of self-described independents.
