Am I the only one who thinks Mitt Romney when they hear the phrase “generic Republican”?

(Rasmussen) — President Obama earns his lowest level of support yet against a generic Republican in a hypothetical 2012 election match-up for the week ending Sunday, August 28.

The latest Rasmussen Reports national telephone survey of Likely U.S. Voters finds the generic Republican earning 48% of the vote, while the president picks up support from 40%. Four percent (4%) prefer some other candidate, and eight percent (8%) are undecided.

Last week, the GOP candidate held a 48% to 43% edge over the incumbent. This is the seventh week in a row a generic Republican has led Obama. Prior to this survey since early May, the Republican has earned 43% to 48% support, while the president has picked up 41% to 45% of the vote.

Rasmussen Reports will provide new data on this generic matchup each week until the field of prospective Republican nominees narrows to a few serious contenders.
