Karen Langley and Clara Ritger caught up with Rob Portman after the possible VP candidate made the Romney camp's pitch to Pa voters yesterday in Lancaster:
Later, in a telephone interview, Mr. Portman said he believes Mr. Romney has a "very good" chance of winning Ohio and Pennsylvania.
"I think that there are a lot of people who have not yet decided, who are in the middle, who tend to make the difference in our states, who are looking for something new," he said.
"They do want to know enough about Governor Romney's background and his experience and, most importantly, his policies to be able to visualize a new and better way, and I think that's the challenge of the campaign."
Asked if the years remaining in his Senate term would make him hesitate to accept an offer to share the ticket, Mr. Portman said he expects to remain in his job.
"I really view myself as staying in the Senate," Mr. Portman said. "I'm just assuming I'm going to stay where I am, stay in the Senate, continue to represent Ohio. I got elected in 2010 for a six-year term. I look at it as an opportunity to serve in an important job. I didn't run to run for something else."
The Republican's campaign will announce the VP choice to supporters via smartphone app. A story at HuffPost wonders whether an announcement will be delayed by the Olympic appearances by Ann Romney's horse, which is due to compete Thursday and Friday.
The Obama campaign too has an app -- it's for grassroots supporters to find campaign events near them, volunteer and find out about the Democrat's policies.
