Tim Scott Hits South Carolina Airwaves for Marco Rubio

Just days after endorsing Sen. Marco Rubio for president, Sen. Tim Scott of South Carolina is hitting the airwaves back home for his GOP colleague from Florida. The ad, obtained ahead of release by Roll Call, appears to be from the same video shoot as the endorsement video, as Scott's shown by his childhood home. "It's a long way from where I grew up to the United States Senate," Scott says in the commercial. "But here in America, all things are possible. That's why I support Marco Rubio." https://www.youtube.com/watch?v=cmEN2-5X9Is The ad's expected to run as part of an existing significant buy in South Carolina, which for the GOP is the host of the third presidential nominating contest, a primary on Feb. 20, in what's billed as the "first-in-the-South" contest. "Marco Rubio understands that here in America, it's not about where you start, it's about where you are going. I'm Tim Scott, and Marco Rubio is the conservative I trust to inspire our country, unite our party, and win in November," Scott says. Scott is himself on the ballot in South Carolina this year, with the seat he's held since being appointed and through a 2014 special election coming up for a full six-year term. The ad's release comes as Rubio has been gaining support from colleagues on Capitol Hill. Sen. Patrick J. Toomey, R-Pa., and House members joined the endorsement list Wednesday. If Rubio is able to do well in both New Hampshire and the Palmetto State, it could cement him as a prospective nominee with appeal to more than one part of the Republican coalition.
