A month ago, the president led Cain by seven percentage points. In March Obama held an 18 point advantage over the businessman and talk show host.

Data released earlier today shows that voters nationwide are evenly divided as to whether or not Cain is qualified to be president — 30% say yes, 33% no, and 37% are not sure. Republicans, by a 49% to 17% margin believe he is qualified while most Democrats disagree. Among Republicans, Cain’s numbers on this question are similar to Rick Perry’s but not as strong as Mitt Romney’s.

In a match-up against President Obama, just 61% of Republicans are ready to vote for Cain. Eighteen percent (18%) would prefer a third option and 11% are not sure. Among unaffiliated voters, 33% prefer Cain, 31% Obama, and 36% aren’t ready to commit to either candidate.
