USA TODAY | Mitt Romney and Paul Ryan arrived in Ohio this week to news of dropping poll numbers and a widening gap in the Buckeye state between the Republican nominee and President Obama. Luckily, they brought back up. Sen. Rand Paul,R-Ky., joined the pair on the road Tuesday, and while he had planned to campaign for Romney, his appearance on the trail couldn't have come at a better time. The libertarian worldview that made him and his father -- Rep. Ron Paul, R-Texas -- populist heroes was on full display in his brief remarks before he introduced Romney and Ryan. Paul told the crowd he was "mortified" by the fact that people in foreign countries are on television burning the American flag and yet still receive foreign aid.
