Cain, Paul, Romney and Gingrich tied in new Iowa poll

With just seven weeks to go before Iowa holds the first nominating contest of the GOP presidential primary, voters in the state remain ambivalent about their choices.

According to a new Bloomberg News poll, businessman Herman Cain leads the pack with 20% support among registered Republican and Republican-leaning voters, followed by Ron Paul at 19%, Mitt Romney at 18% and Newt Gingrich at 17%. The poll, which was taken Nov. 10-12, has a margin of sampling error of plus or minus 4.4 percentage points, meaning the four candidates are in a statistical dead heat.
