McCain saw the largest decrease in support over the past four months. He fell from 6.6 percent support in March to only 1 percent now, a decrease of more than 5.5 percent.
Hillary is also leading in Iowa when those polled were asked:
…an open-ended question: to name the candidate they support for president in the 2008 election. They could name any candidate from either party.
Among the sample of all 907 registered voters, Sen. Hillary Rodham Clinton, D-N.Y., led with 18 percent support, an increase of 4.5 percent since the March UI poll.
Sen. Barack Obama, D-Ill., was second with 13.8 percent, an increase of 2.9 percent.
Romney saw the largest increase in support. He was supported by 8.9 percent of all registered respondents this time – nearly double his March support of 4.7 percent.
McCain will have to sprint just to catch up to the marathon.
