As we all know, a visit from Sarah Palin ensures a heap of buzz for any Republican candidate. But the former Alaska governor is not the only popular GOP figure on the trail this summer. According to a new profile on CQPolitics.com, Sen. Scott Brown (R., Mass.) is a rising star:

Brown’s scheduled events last weekend included attending a fundraiser Friday for Rep. Rob Wittman (R-Va.) and delivering the keynote speech Saturday at the Nebraska state GOP convention in Fremont — an invitation extended by Sen. Mike Johanns (R).
Cornyn said Brown is set to travel to Tennessee soon to attend a fundraiser. The Senator has appeared at several NRSC fundraisers at the request of the committee.
Brown has campaigned for Sen. John McCain (Ariz.), has been helping Rhode Island state Rep. John Loughlin, who is running for the seat being vacated by Rep. Patrick J. Kennedy (D), and previously aided Rep. Charles K. Djou by asking his list of Aloha State donors to contribute to the former Honolulu city councilman’s special election campaign.
Brown also campaigned for Tim Burns, who lost the special election race for Pennsylvania’s 12th district.

Still, as he looks toward his 2012 reelection bid, the Bay State remains Brown’s focus. “He is a Republican and wants to help other Republicans be successful. But I think you’ll find he’ll be most active in Massachusetts, although there will be some out-of-state races where he pitches in,” said Eric Fehrnstrom, Brown’s chief political adviser, to the website.
