Marion, Ohio (CNN) -- Does Vice President Joe Biden know something no one else knows: the outcome of the election?
On Wednesday, the vice president joked as if he did, stating that Mitt Romney is "not going to be elected."
It came during a campaign event in Marion, Ohio, as a baby's piercing cries interrupted a stretch of audience silence during the vice president's speech.
"Look, I don't blame that baby for crying," Biden said. "You know what, she just realized what it means if Romney gets elected," he added, prompting laughter from his audience. It's a joke the vice president also made on Saturday in St. Augustine, Florida, as another baby wailed in the crowd.
Except this time, Biden added an apparent guarantee.
"Hi baby. How are you? It's ok. He's not going to get elected," Biden said. "You're going to be okay."
Candidates commonly express confidence at their electoral prospects. Both President Obama and Romney - the Republican presidential nominee -- have repeatedly rallied supporters around versions of the line: "We're going to win this election."
What's not as common is for a candidate to expressly state that an opponent will lose.
Biden's comments came at the final campaign rally over a three-day swing through the critically important Buckeye state. Moments before, the vice president slammed Romney's economic plans by invoking an iconic conservative president: Ronald Reagan.
As he's frequently claimed, Biden stated that Romney's proposals would eliminate Medicare, which services the elderly, and hurt Medicaid, a program for the poor.
"All in the service of tax cuts for the very wealthy," Biden thundered. "It is not fair. It is not right. It is not good economics. It is not good for growing the economy."
"They say it's just like what Ronald Reagan did. Ronald Reagan did not do this. I served with Ronald Reagan. Ronald Reagan had a massive tax cut. When it didn't work, he ended up raising taxes 11 times. Ronald Reagan did not do this."
Biden added: "Ronald Reagan couldn't even be their standard bearer this time based on what he did."
During Biden's only debate with Republican vice presidential nominee Rep. Paul Ryan, the two sparred over similarities between economic proposals enacted by the 40th president and those that Romney proposes.
The Romney campaign was swift in responding to Wednesday's charges from the president and vice president.
"Vice President Biden and President Obama showed again today that their campaign is getting smaller and smaller as Election Day approaches. With no plan to grow the middle class, Americans know another four years of Obama-Biden policies will mean more of the same: falling incomes, higher taxes, and more debt.," Romney spokesman Ryan Williams said in a statement.
"In two weeks, they will choose Governor Romney's positive agenda over the Obama campaign's increasingly desperate attacks."
Meanwhile, Biden leveled another quip at the GOP presidential nominee.
Early on during his speech, the vice president noted the various times Romney agreed with the president during Monday's third and final presidential debate.
"Half the time, in this last debate, I didn't know whether or not Gov. Romney was there to debate Barack Obama or endorse Barack Obama," Biden said, prompting laughter.
"I wasn't sure. I'm serious."
