Arvada, Colorado (CNN) - Three days before the presidential election, Vice President Joe Biden made a prediction: the sun will go down on Mitt Romney's presidential hopes on Tuesday.
During a rally in Colorado, the vice president teed up his premonition.

"You saw those debates?" Biden asked the crowd. "You began to wonder. Gov. Romney and Congressman Ryan seem to be running as fast away from their positions as they can. It's like watching a guy, a little kid trying to outrun his shadow, man! It keeps coming up to him. It's like whoa!"
"It's still there," Biden added. "Shadow doesn't go away until the sun goes down. It's going down Tuesday night! That's what's going down."
Apparently not intent on political slams with just one daytime metaphor, the vice president used another: referring to the upcoming Daylight Savings time – where Americans will turn their clocks back an hour early Sunday.
"It's Mitt Romney's favorite time of the year because he gets to turn the clock back," the vice president said, prompting laughter and applause from supporters. "He wants to turn that clock back so desperately. This time he can really do it tonight."
The Obama campaign has frequently claimed that Romney's economic and social policies are throwbacks to yesteryear.
Biden's comments came at Arvada High School in the City of Arvada in the Denver metropolitan area. The city is located in Jefferson County, Colorado's fourth most populated. In 2008, then Sen. Barack Obama won the county by nine points over Sen. John McCain, helping him win the Centennial State by nine points.
Current polls do not forecast such an advantage in Colorado for the Obama campaign. A recent CNN/ORC International poll showed that 50% of likely voters support Obama with 48% for Romney, well within the survey's margin of error. The poll is reflective of others that showed a tight race in Colorado.
At the event, Biden also continued to lay out nuggets of the campaign's closing argument. On one issue, the vice president was especially provocative.
While repeating his frequent slam against Romney's secretly-recorded comments that 47% of Americans are dependent on the government and refuse to take responsibility for their lives, Biden asked a question about Republican policies that, he claimed, favor the wealthy at the expense of the middle class.
"I'm trying to figure…why would they do this stuff?" the vice president asked. "Because they're not bad men."
Biden continued: "It's because, I truly believe, if you look at all their policies, the fundamental dividing line between the president and me and Mitt Romney and Paul Ryan who talks about the culture of dependency and all this stuff, here's what I think the fundamental difference is: I don't think, I don't think they have confidence in average Americans."
"I think they really do believe, unless the enlightened, the wealthy, the powerful are absolutely able to have their hands on the wheel and direct everything, that we're in trouble."
Meanwhile, the man who wants the vice president's job also framed closing arguments on Saturday.
In another battleground state, Ohio, Ryan stressed that his team's message is far more positive than that coming from the Obama campaign.
"In 2008 he appealed to our highest aspirations, now he's appealing to our lowest fears," Ryan said of the president.
