BOSTON (AP) -- Mitt Romney is declaring "I'm going to get this nomination" as Republicans in 10 states had contests to pick a challenger to President Barack Obama.
Romney on Tuesday congratulated rivals Newt Gingrich for his win in home state Georgia and Rick Santorum for wins in Oklahoma and Tennessee. Contests are still going elsewhere on the single largest day of voting so far in the nominating battle.
Romney is telling supporters that it's been a long road getting to Super Tuesday and, in his words, "my opponents have worked very hard."
Romney is keeping most of his election night remarks honed on Obama, again criticizing the incumbent he wants to vote from office in November. He warns supporters that Obama would be "unrestrained" if he wins a second term and would trample Americans' freedoms.
