John McCain has started to build an almost insurmountable lead in the GOP presidential race.."](CNN) - Super Tuesday positioned Sen. John McCain as the clear Republican front-runner, while a split decision in the Democratic race may eventually help Sen. Barack Obama, according to CNN's political analysts.
McCain extended his lead in the GOP race with impressive coast-to-coast wins from New York to California, while former Arkansas Gov. Mike Huckabee carried states in the South. Former Massachusetts Gov. Mitt Romney won seven races, including his home state of Massachusetts.
"I think we did achieve clarity. John McCain will be the Republican nominee," CNN analyst Jeffrey Toobin said. "Mike Huckabee did better than a lot expected. If you look at the delegates, there is no way either Huckabee or Romney can catch up. I think we did learn that much."
