Even though at least one other poll I've seen indicates that voters seem to favor Obama's illegal order, it's not changing their opinions about whether he should be re-elected. This issue, like gay marriage, appeals only to a small voting base. In fact, this issue probably has its most appeal among people who are ineligible to vote and therefore can't do much to help Obama.
UPDATE: I've updated the headline to eleven. Today, Rasmussen has Romney up 48 - 44% over Obama. Romney inches towards the magic 50% number as Obama languishes.
In the long run I have to believe this will be a net loser for him.
