CINCINNATI, Ohio -- Vice presidential nominee or not, Sen. Rob Portman (R-OH) will not be relying on an iPhone app to find out the fate of his political future.

Thought to be on Mitt Romney's VP shortlist, the Ohio senator told reporters on Saturday that he still has not downloaded the mobile phone application that promises to inform users of the pick "before the press and just about everyone else (except maybe Ann)." He first revealed on Thursday that he did not have the app, and that seems to have remained unchanged over the past 48 hours.

"I haven't actually gotten the app myself.  I have an iPad all full of apps, half of which I never get time to use anyway.  But we'll see," he said. "I assume I'll hear it other ways."

He told a local Cincinnati news station, "I imagine that's not how they probably would communicate it to me, but who knows."

His disinterest in the app is in contrast with the Romney campaign and at least one other potential VP shortlister.  Along with campaign staffers, Sen. Marco Rubio (R-FL) has been promoting the technology through twitter.

It would be hard to argue that Portman has not already earned a phone call or face-to-face meeting with the Romney campaign to find out the news.  He attended volunteer appreciation events at two Romney Victory offices on Saturday as part of the "Buckeye Blitz" happening throughout the state.  It's just the latest in a long line of events he's done in his home state on behalf of the presumptive nominee.

Asked what his responsibilities might be if chosen as Romney's No. 2, Portman said, "I would work very hard for Mitt Romney, but that's what I'm doing anyway."

That certainly will remain true at the beginning of this week when the Cincinnati native travels to the northeast part of the state to stump for the former governor. And while Congress is on its August recess he also plans to travel out of state to campaign for Romney as well.
