Romney touts fiscal discipline in his latest campaign ad.

WASHINGTON (CNN) - Republican presidential hopeful Mitt Romney will hit television airwaves in Iowa and New Hampshire Wednesday with a new ad touting his fiscal discipline. It’s the latest effort in the former Massachusetts governor's aggressive advertising push in the early-voting states.

The new ad, titled "Work Like Crazy," is comprised of clips from past speeches in which Romney vows to cut taxes and spending.

"Government is simply too big," Romney says in the ad. "State government's too big. The federal government's too big. It's spending too much."

Romney first launched ads in Iowa and New Hampshire in early February. His poll numbers in the two crucial campaign states have steadily increased since then.

A CNN/WMUR poll released last week found Romney with an 8-point edge in New Hampshire over both Arizona Sen. John McCain and former New York City Mayor Rudy Giuliani. Meanwhile, a Des Moines Register poll released late last month showed Romney with a 12-point lead over McCain and a 13-point lead over Giuliani in Iowa.

McCain and Giuliani have yet to run campaign ads.
