WASHINGTON--Mitt Romney's team is continuing on Saturday--in ad buys in battlegrounds Ohio, Wisconsin and Virginia--to woo undecided voters with the theme of what a "disappointment" President Barack Obama has been.

Per the RNC: "The Republican National Committee's independent expenditure is out with a new TV ad "Golden." After spending $800 billion on a stimulus program that didn't work and experiencing four years of massive spending with no end in sight, it's time to make a change."

The independent expenditure has put in $4 million in reserved air time, according to the RNC.

The 30-second spot uses the "fool me once, shame on him, fool me twice, It's time to make a change," pitch playing for swing voters who cast a ballot for Obama in 2008.
