With victories in Vermont, Ohio, Texas and Rhode Island on March 4, Sen. John McCain erased any uncertainty that he would be the Republican presidential nominee in 2008.

Super Tuesday 2.0 locked up Sen. McCain's long awaited shot at the presidency in the general elections.

“I am very pleased to note that tonight, my friends, we have won enough delegates to claim with confidence, humility and a sense of great responsibility that I will be the Republican nominee for president of the United States,” McCain told supporters in Dallas.

McCain won winner-take-all Vermont with 72 percent of the vote, picking up the state's 17 delegates.

Gov. Mike Huckabee followed McCain in the Green Mountain State with 15 percent of the vote. Rep. Ron Paul finished last among Republicans with with 7 percent of the vote.

John McCainMcCain also won Ohio with 58 percent of the vote and picked up the state's 58 delegates. Huckabee again finished second with 33 percent of the vote, Ron Paul was last with 5 percent.

McCain received 57 percent of the male vote in Ohio and 60 percent of the female vote. He also received 58 percent of the white vote. 

With 87 percent of the precincts reporting for Rhode Island, McCain is the projected winner. He has 65 percent of the vote and has won at least 10 delegates. Huckabee follows with 22 percent of the vote, Ron Paul finished third with 8 percent. Only two percent of voters are uncommitted.

While the aforementioned states were important victories, the Lone-Star State's 137 delegates pushed McCain over the edge. The Arizona senator received 58 percent support in Texas, better than Huckabee's 33 percent. Despite representing Texas' 14th district, Ron Paul only came away 5 percent statewide. Like Rhode Island, two percent of Texas voters were uncommitted.

Though McCain won Texas, he split key demographics fairly evenly with Huckabee and Paul according to CNN Exit Polls. 52 percent of males, 52 percent of the females, 53 percent of whites and 45 percent of the Hispanic voters favored McCain in Texas. 

McCain will now focus his energy on choosing a running mate, unifying the Republican party and on his democratic opponent.

"It's now important that we turn our attention not to what could have been or what we wanted to have been, but now what must be -- and that is a united party," Huckabee told to a crowd of supporters in Dallas.
