Cue the vice presidential buzz.

The freshman congressman has become famous for his First in the South Presidential Town Hall series. He has hosted nearly every presidential candidate, and now has set his sights on governors.

“While Governor McDonnell is not currently a candidate for president, he will play a key role in the 2012 election and beyond,’’ Scott said. “He has a proven record of job creation and keeping taxes low in Virginia – a state the GOP must win in 2012. Our voters are eager to hear his views on the presidential field, and on how we will defeat President Obama.”

It’s the latest national attention for McDonnell, chairman of the Republican Governors Association, who spoke to New Hampshire Republicans in September and has been asked to do the same at the Missouri GOP’s largest event next month.

Saturday’s town hall, set for 75 minutes, will allow for questions from a live audience and through Scott’s Web site. It begins at 5:30 p.m.

“Tim is a leading voice in the new wave of bold and innovative conservative leaders who are committed to getting our nation’s economy back on track and our fiscal house in order,’’ McDonnell said. “I look forward to joining him in South Carolina to speak directly with his constituents about the serious challenges facing our nation, and the tremendous opportunities we have to make government smaller and smarter, and get more Americans working again.’’
