Republican presidential candidate Mitt Romney is hoping to draw voter support from the swing state of Colorado after campaign stops there, Thursday.
About 2,000 supporters showed up to hear Romney speak earlier in the day in Golden, Colo.
While there, he outlined his five-point program he called the "Romney Plan for a Stronger Middle Class."
"The more they raise taxes, the more they lower growth. It's like a dog chasing its tail," Romney said, referring to the Democrats' plan for the economy.
Later Thursday, Romney planned to raise funds and mingle with Republican governors who are meeting in Aspen.
Among them are vice presidential prospects, including New Jersey Gov. Chris Christie, Louisiana Gov. Bobby Jindal, and Virginia Gov. Bob McDonnell.
Meanwhile, President Barack Obama is also on the road in two swing states -- Florida and Virginia. First lady Michelle Obama is campaigning in New Hampshire, another battleground state.
His campaign released a new class warfare ad called "worried." The ad criticizes Romney's tax plans as partial to the wealthy and tough on the middle class.
"You work hard, stretch every penny, but chances are you pay a higher tax rate than him," the ad's narrator says.
"Now he has a plan that will give millionaires another tax break and raises taxes on middle class families by up to $2,000 a year," the narrator continues.
The new 30-second spot airs in Virginia, New Hampshire, North Carolina, Florida, Ohio, Iowa, Colorado, and Nevada.
