(CNN) - John McCain's campaign launched a new ad Thursday that sharply criticizes Barack Obama's tax policies.
The ad, which also continues the campaign’s effort to paint the Illinois senator as a mere celebrity, says Obama's tax policies will lead to an "economic disaster."
"Obama's new taxes could break your family budget," the ad's announcer says. "Higher taxes. Higher gas prices. Economic disaster."
The campaign says the 30-second spot, called Taxman, will air in "key states."
Obama has proposed cutting taxes on middle-income Americans while raising those for families earning over $250,000. Writing in the Wall Street Journal Thursday, Obama economic advisers Jason Furman and Austan Goolsbee defended Obama's proposals.
"Sen. Obama believes a focus on the middle class is appropriate in the wake of the first economic expansion on record where the typical family's income fell by almost $1,000," Furman and Goolsbee wrote.
McCain has proposed extending President Bush's tax cuts, including those of high-income earners.
