Rob Portman won't run for president in 2016

Portman began calling allies Monday to let them know he didn’t plan to run nationally, sources familiar with the calls told POLITICO.

In a statement released Tuesday, Portman said he didn’t think he could run for president in 2016 while also serving effectively in the Senate.

“With the new Republican majority, I see a real opportunity over the next two years to break the gridlock in Washington and actually get things done to help Ohioans and all Americans,” he stated. “That’s where I believe I can play the most constructive role.”
