DENVER -- The major party contenders for President of the United States have two ads running that tout their policies and their resume, but some of the claims in the ads are misleading, lack context or are false.

"A comprehensive, bi-partisan plan to lower prices at the pump, reduce dependence on foreign oil through domestic drilling,” an ad for Republican John McCain says.

But one of his own advisers was quoted recently in the Los Angeles Times saying that additional drilling will not fix the current energy crisis and experts say it could take more than a decade for new off-shore oil wells to produce gas for consumers.

So it’s fiction to imply that domestic drilling will reduce dependence on foreign oil -- at least anytime soon.

McCain staffers say drilling is just part of his overall energy plan, which will help reduce dependence on foreign oil.

Democrat Barack Obama has similarly questionable claims in his newest commercial.

“Slashed the rolls by 80 percent, passed tax cuts for workers, health care for kids...," the Obama ad says.

Obama did sponsor legislation addressing welfare to work programs but the drastic reduction in welfare rolls is attributed to federal legislation that he had nothing to do with. So this claim is fiction.

Obama staffers did not directly address that claim when asked about it.

Other claims from both candidates are not outright false but are misleading.

“And champion energy alternatives for better choices and lower costs,” McCain’s commercial says.

But in the U.S. Senate, McCain voted against several bills or amendments to legislation that would have promoted alternative energy. His spokesman said that was because the measures did not rely on the free market to solve the problem or included tax breaks for oil companies.

The new Obama ad says "he passes a law to move people from welfare to work."

He was a sponsor of the law but it had to be passed by the whole Illinois General Assembly and signed by the governor so he did not single-handedly pass a law. The commercial also cites only Obama’s work in the state legislature, leaving critics to question what he has done in his time in the U.S. Senate.

Both of these claims can be seen as misleading.
