Romney will announce his choice for Vice President in Norfolk, Virginia at 8:45am EST,” Romney campaign spokesman Lenny Alcivar told reporters in an email this evening.

The announcement is being made at the USS Wisconsin. It’s still unclear whom he will choose, but the odds that it is Rep. Paul Ryan, R-Wis., seemed to increase when National Review’s Robert Costa noted that a charter plane flew from Boston to Ryan’s hometown of Janesville, Wis., today.

Presidential campaigns, however, are notorious for head fakes during the running mate selection process.

If it is Ryan, Romney might have been hinting at the selection when he described his intended running mate to NBC’S Chuck Todd.

“I certainly expect to have a person that has a strength of character,” Romney said. “A vision for the country, that, that adds something to the political discourse about the direction of the country. I mean I happen to believe this is a defining election for America; that we’re gonna be voting for what kind of America we’re gonna have.”

Steven Hayes and Bill Kristol of The Weekly Standard wrote this evening that “the Romney campaign has begun to prepare a vigorous effort in support of Paul Ryan if he is selected as Mitt Romney’s vice presidential pick—something now likely to happen soon,” although they conceded that “this of course does not mean the Wisconsin congressman will necessarily end up as Romney’s running mate.”
