(CNN) – Vice President Joe Biden invoked the Etch A Sketch controversy to attack Mitt Romney's economic proposals during a speech in the battleground state of Florida Friday.
Biden specifically targeted Republican presidential frontrunner Mitt Romney's support of the "cut, cap and balance" while mocking the Etch A Sketch comment from senior Romney adviser Eric Fehrnstrom.

"Governor Romney supports cut, cap and balance and which is yet another demonstration that there is no daylight between Gov. Romney and Republican leaders on the most important issues facing this country," Biden said. "And not even Romney's Etch A Sketch can change that. He is not going to be able to do that. He may buy a new one, but he can't do it.
Fehrnstrom set off a fire storm after he compared the differences between a general and primary election to an Etch A Sketch, during an appearance on CNN Wednesday.
"Cut, cap and balance" is a Republican-backed proposal that passed the House of Representatives in July 2011. Those who signed the pledge vowed to oppose any debt limit increases unless they included cuts and caps on spending, as well as the passage of a Balanced Budget Amendment to the U.S. Constitution.
Romney has said he supports the pledge as a first step toward reforming government.
Biden's speech Friday in Coconut Creek, Florida was the second in a series of speeches the former Delaware senator is expected to make about the economy. Last week he addressed a United Auto Workers union hall in Ohio, a state likely to be competitive in 2012 election. The Obama-Biden ticket captured Florida and Ohio in the 2008 election with 50.9% and 51.2% of the vote respectively.
The Romney campaign countered with criticism of President Barack Obama.
"President Obama entered office promising to reform our entitlement programs and cut the deficit in half. He failed miserably on both counts," Andrea Saul, a campaign spokeswoman, said in a statement. "After three years of trillion-dollar deficits and a historic increase in the national debt, we need a new president – not four more years of broken promises and empty rhetoric."
Biden, who is also expected to campaign in Iowa, New Hampshire, Virginia and Pennsylvania, criticized Republican-backed measures that he said will negatively impact Social Security and Medicare.
"Make no mistake about it. If the Republicans in Congress and their amen corner of Romney, Santorum and Gingrich – if any of them get their hands on the White House, the keys to the White House I promise you, you will see Medicare ended as we know it," Biden said.
