Democrats may have run from President Obama during midterm elections, but Comedy Central late-night host Stephen Colbert welcomed him with open arms Monday — and was rewarded with a big turnout, audience-wise.  With POTUS as his guest (and The WORD anchor), Colbert’s show jumped nearly 50 percent compared to its season average. An average of 1.732 million people watched Monday night’s telecast, in which Colbert was telecast from George Washington University in Washington, D.C., the night after hosting the Kennedy Center Honors in town, for his soon-to-be-new employer, CBS.

Colbert’s most recent original episode, last Thursday, had averaged 1.092 million viewers.

Monday’s episode, in which Obama took over The WORD segment to talk about Obamacare, clocked 520,000 18-34 year olds, compared to last Thursday’s 278,000; calendar year to date, the show is averaging 364,000 viewers in that demo. More than half Obama’s audience  — 953,000 viewers — was aged 18-49, compared to calendar year’s 628,000 viewers in the bracket.

“I will say I felt more powerful behind that desk,” Obama told Colbert at the start of last night’s interview, after delivering The WORD — which he’d promoted to The DECREE because he’s president.

“With great power comes medium cable ratings,” Colbert said.
