*Worst-Case Scenario: Hillary loses the first two states (which I don't think she will) and still ends up as our nominee!

From Slate:

Even if Hillary staggers out of New Hampshire with her second loss in as many contests, she’ll still have the same massive advantages she enjoys today: the campaign and super PAC cash, the ground game, the endorsements, the pledged superdelegates, and the general support of a party establishment that won’t soon forget that her challenger is not technically even a part of the Democratic Party. An unexpected loss in Iowa and a less surprising one in New Hampshire wouldn’t change that.

She’d also have a chance to get back on her feet—and fast. Consider what comes next: Nevada (Feb. 20) and South Carolina (Feb. 27), two significantly more diverse states than lily-white Iowa and lily-whiter New Hampshire, and two places where Clinton currently enjoys massive leads in the polls. According to the RealClearPolitics rolling average, Clinton holds a 20-point advantage in Nevada and a whopping 40-point lead in South Carolina. March brings better news still for the former secretary of state, starting with a Super Tuesday slate that includes friendly territory in the form of southern states like Arkansas, Alabama, Tennessee, Texas, and Virginia. The rest of the month, meanwhile, includes several big, delegate-rich contests that she won eight years ago during her battle with Barack Obama: Michigan, Florida, and Ohio. Yes, Sanders could have the momentum this time next month, but it’ll be on him to to find a way to keep it as he heads into significantly more challenging terrain than Iowa or New Hampshire, which were always going to offer his best chance at pulling off an early upset or two.

None of this is to say that Clinton has the nomination locked up already. She doesn’t. But if Iowa and New Hampshire are must-wins for anyone, it’s Sanders. Hillary can—and likely would—survive a slow start and still be the one standing on stage at the Democratic National Convention when the balloons come down this summer. Bernie, though, has no such margin of error.
