No, it's not over yet. But at this rate Mitt Romney's rivals won't catch him unless they pull off an unlikely fight at the Republican National Convention in August.
Romney is on a delegate-winning pace to secure the nomination in June, and at their current rate none of his GOP foes will reach even half the number needed.
The former Massachusetts governor's six victories on Super Tuesday netted him over 200 delegates to the party's convention -- more than twice as many as any other candidate. And to date, Romney has won 55 percent of the delegates at stake in primaries and caucuses.
At that pace, Romney won't reach the 1,144 delegates needed to clinch the Republican nomination until summer. That provides a lot of opportunities for slip-ups and intrigue -- and plenty of incentive for Rick Santorum and Newt Gingrich to stay in the race and try to make up ground.
Romney is projecting confidence.
We've got the time and the resources and a plan to get all the delegates, and we think that will get done before the convention," he said Wednesday on CNBC. Still, he also said he was "prepared to fight all the way" to the convention if needed.
