NEW YORK (AP) — Mitt Romney has been on the national political stage for nearly a decade — through two presidential bids, countless campaign events and millions of dollars spent on TV ads. But most voters still don't know him.

Romney has started to introduce himself to voters in earnest through a combination of carefully selected media appearances and biographical ads — before President Barack Obama's efforts to define Romney in a negative light cripple his candidacy.

After a recent trip abroad, Romney is entering a period where the media glare will shine even brighter.
