President Barack Obama and reality television celebrity Kim Kardashian have something in common, according to Mitt Romney – they don’t know how to keep a promise.

“I’ve been looking at some video clips on YouTube of President Obama, then-candidate Obama, going through Iowa, making promises,” Romney said during a campaign stop in Council Bluffs, Iowa, on Sunday.

“I think the gap between his promises and his performance is the largest I’ve seen, well, since the Kardashian wedding and the promise of until death do we part,” said the Republican presidential candidate.

Kardashian filed for divorce on Oct. 31, just 72 days after marrying basketball player Kris Humphries in a lavish televised wedding that was billed as a “fairytale.” She is one of the highest-paid reality stars on U.S. television, with 2010 earnings estimated at $6 million from her TV show, clothing line, perfume, jewelry and tanning cream and other product endorsements and appearances.

In October, First Lady Michelle Obama told a group of reporters that her husband didn’t like their daughters, Malia and Sasha, watching the Kardashian reality television shows.
