Mitt Romney is opening his first formal day as a 2012 Republican presidential contender with a direct challenge to the man he wants to replace.
He says, "Barack Obama has failed America."
In excerpts of his announcement speech, scheduled for noon Thursday, Romney makes the case that he is positioned to defeat the incumbent Democratic president and turn around the country. The former Massachusetts governor and business executive says the United States took a chance on Obama in 2008 and instead got only promises and slogans.
Romney, who ran for the GOP nomination four years ago and came up short, is set to enter the race at a barbecue on a farm in Stratham, N.H.
