Most Americans don't know enough about Sen. Rob Portman (R-OH), a man pegged by many as a potential running mate to Republican nominee Mitt Romney, according to a new poll released Friday.
The latest ABC/Washington Post poll tracks Americans' opinions of three current and former elected officials considered to be possible vice presidential nominees on the Republican ticket: Portman, Sen. Marco Rubio (R-FL) and former Florida Gov. Jeb Bush.
Among those surveyed, 51 percent have no opinion of Portman, a reflection of his status as a low-key senator. Thirty percent have an unfavorable view of the Ohio senator, while 19 percent view Portman favorably. Rubio and Bush fare a bit better — at least in terms of recognition. Twenty-nine percent view Rubio favorably, compared 36 percent who have a favorable view of Bush. Only 19 percent have no opinion of Bush, while 39 percent feel the same way of Rubio.
