Former Rep. Rob Portman (R) holds on to a slight lead over both potential Democratic opponents in a new Rasmussen poll of the Ohio Senate race (500 LVs, 2/5-6, MoE +/- 4.5%).

General Election Matchups
Portman 43 (-1 vs. last poll, 1/12)
Fisher 39 (+2)
Und 13 (-1)

Portman 42 (-1)
Brunner 38 (-2)
Und 15 (+2)

Lt. Gov. Lee Fisher (D) polls at the same level as Secretary of State Jennifer Brunner (D) after having underperformed her for most previous surveys. Fisher is the choice of most establishment Democrats, while Brunner has struggled to raise money to run a viable campaign. And yet in the RCP Averages for Ohio, she runs closest with Portman, trailing by 4.0 rather than Fisher's 5.3 percent deficit.

President Obama's job approval rating is 49 percent, while 51 percent disapprove. That's a slight improvement from the 46/54 split in January. Gov. Ted Strickland (D) has a 46 percent approval rating, up 3 points from January.
