Palin, a conservative favourite who is stoking speculation she will run for president, claimed in a recent television interview that she could beat Obama.
"You know, I don't speculate on what's going to happen two years from now," Obama told ABC News late on Tuesday when asked if he could beat Palin in a race for president.
"What I'm saying is, I don't think about Sarah Palin," Obama said.
