Romney plans

Republican presidential contender Mitt Romney is touting his proposal to expand U.S. military power in the latest commercial aimed at boosting his name identification.

The spot features slides of the former Massachusetts governor appearing with troops and addressing a conservative political conference.

The candidate has proposed expanding the military by 100,000 troops and committing 4 percent of the nation's gross domestic product to military spending.

Romney began his wave of national advertising on April 25, airing commercials on national cable networks at a cost of some $2 million. Most of them will run on Fox News, a strategic effort by the Romney camp to reach conservative voters.

Romney also renewed an ad campaign in Iowa and New Hampshire. The new spot will air before both the local and national audiences.

The former governor raised $21 million during the first quarter and began the second quarter with nearly $12 million in the bank, the most among the Republican candidates.
