Sen. Rob Portman of Ohio will not run for National Republican Senatorial Committee chairman in Wednesday's leadership elections, according to a GOP aide familiar with his decision.
"He was honored to hear from so many asking him to consider running," the aide said. "It was not something he had ever given much thought to, but he decided it's best to keep his focus on some of these huge policy issues that we face as a nation."
Portman's decision means the post will likely go to Sen. Jerry Moran of Kansas, the only candidate to publicly express interest in the post. Moran told Roll Call last week that he's been running for the seat for at least six months, lobbying his colleagues for support. He announced last week that he had enough votes to win the race — although he declined to give a specific figure.
Portman's decision may come as a disappointment to Senate Republicans who praised his fundraising prowess, both in his southern Ohio base and in financial centers such as New York. In 2012, Portman was the top fundraiser for the NRSC in the freshman class.
