Vice President Joe Biden speaks at a campaign rally in Arvada, Colorado criticizing Romney's policies towards China as 'malarkey'.

ARVADA, Colo. -- Ka-zing.

Three days before the election, Vice President Joe Biden pegged his newest critique of Republican presidential nominee Mitt Romney to the semi-annual inconvenience of adjusting clocks for Daylight Savings Time, which occurs tonight.

"It’s Mitt Romney’s favorite time of the year -- because he gets to turn the clock back!" Biden told a crowd of hundreds at a suburban Denver high school.

In his remarks, the vice president accused Romney of embracing social policies out of an earlier era, pointedly noting the GOP nominee's voiced enthusiasm for "getting rid of" Planned Parenthood.

"With all the issues facing the country, Gov. Romney has focused on for the last three months [that] he's going to get rid of Planned Parenthood" Biden said. "And by the way, he doesn't even know he doesn't control Planned Parenthood."

"He should talk to Big Bird!" he added, referencing the scuffle over public broadcasting funding that broke out during one of the presidential debates.

(In context, Romney said last spring he was going to "get rid" of federal funding for Planned Parenthood, not get rid of the entity itself.)

Biden has two events scheduled in swing state Colorado Saturday. He will campaign Sunday in Ohio.
