The presidential sit-down drives the CBS show's ratings up 60 percent from its Tuesday average.

David Letterman is the latest to benefit from interest in the election.

Last night's Late Show, which featured a visit from President Barack Obama, saw a huge ratings boost for the talker. It posted its highest overnight rating since February 2010.

The appearance, which saw the commander-in-chief join the host in poking fun at Clint Eastwood's "empty chair" speech from the Republican National Convention, earned a 4.0 household rating and 10 percent share. That bests the weekly average for last season by 67 percent and the year-to-date Tuesday average by 60 percent.

The show fared especially well in its native New York, where WCBS-TV delivered a whopping 495,000 viewers and a 2.6 rating with adults 25-54. It's the best demo showing in that market since 2006.

Craig Ferguson and the Late Late Show also got an Obama boost. The show, earning a 1.9 rating and seven percent share, also hit a two-year high.
