Republican Mitt Romney, flush with cash from early fundraising, this week will air his first presidential campaign ad to introduce himself to voters in several early voting states. The 60-second spot describes the former Massachusetts governor as a "business legend" who "rescued the Olympics" and "turned around a Democratic state."

Romney himself adds: "This is not a time for more talk and dithering in Washington. It's a time for action."

The ad is set to air starting Wednesday in Iowa, New Hampshire, South Carolina, Michigan and Florida.

It is the first ad by a top-tier contender in a campaign experts believe will cost more than $1 billion by the time it ends in November 2008.

Madden refused to reveal the cost or scope of the ad buy, except to say both the full ad and an abridged, 30-second version will air in "select markets" in the five states.
