Clinton's Super Tuesday wins narrows Sanders path

Sanders' insurgent campaign caught fire this fall, drawing huge crowds and raising questions about the breadth of Clinton's appeal within her own party.

[...] as the contest has expanded past the largely white electorates of Iowa and New Hampshire, Sanders has struggled to capture support from the minority voters who make up a large piece of his party.

After her wins on Super Tuesday, Clinton is nearly halfway to claiming enough delegates to win the nomination, when you include her superdelegates, the party insiders free to pick either candidate.

Beyond Vermont, Sanders' wins came in Minnesota, Colorado and Oklahoma, where working-class white voters play a bigger role in Democratic contests.

The former secretary of state's team argues that once Sanders loses the delegate lead, it becomes very difficult to regain control of the race because delegates are awarded proportionally.

By March 15, nearly half of the Democratic delegates will have been awarded, giving Clinton a chance to build a large enough lead to make it nearly impossible for Sanders to capture the nomination.

Sanders and his team showed no signs of exiting the race, with senior strategist Tad Devine saying he sees no scenario where Sanders gets out before the party convention in July.

[...] Sanders has little financial incentive to end his campaign, which reported raising more than $42 million in February — $12 million more than Clinton and enough to keep going well into the spring.
