Updated 9:48 p.m. ET - Mitt Romney declared victory in his quest to become the Republican presidential nominee on Tuesday and kicked off his general election campaign against President Barack Obama in earnest following a clean sweep of primaries in the Northeast.
Romney's performance in Connecticut, Delaware, New York, Pennsylvania, and Rhode Island allowed him to cap a tumultuous GOP primary cycle that extended longer than many expected. Romney's march toward the 1,144 delegates needed to secure the nomination appeared, at this point, to be all but a formality.
And, eager to begin prosecuting his case against Obama, Romney took a victory lap in the general election swing state of New Hampshire -- rather than appearing in any of the states hosting nominating contests tonight or in the future -- to declare, "a better America begins tonight."
"Tonight I can say thank you, America," Romney told a cheering crowd in the Granite State. "After 43 primaries and caucuses, many long days and more than a few long nights, I can say with confidence -- and gratitude -- that you have given me a great honor and solemn responsibility. And, together, we are going to win on Nov. 6."
