Iowa Polling: SUSA and Rasmussen 2008

SUSA polled registered voters until the June poll, when it polled likely voters. Polls surveyed between 528 and 600 respondents.



All Rasmussen polls surveyed 500 likely voters.

Among the Bush states, Iowa is the most likely to be flipped by Obama. Obama has treated Iowa as his second home in his campaign thus far. It was the key to his primary victory over Sen. Clinton. His consistent lead there reflects the fact that 177 of his 686 campaign appearances (26%) have been in the Hawkeye State. The next closest state in total campaign appearances is New Hampshire with 52.
