For Hillary Clinton, the latest polls have some good news and some bad news.
For one, she still holds a massive 67% to 31% lead over Bernie Sanders in the early primary state of South Carolina. The South Carolina Democrats are overwhelmingly black, one of the few demographic groups that strongly supports Clinton.
But the news isn’t as good in the two states that vote before South Carolina.
The first nominating contest of the 2016 election is in Iowa. There, she leads Sanders by just five percent, 50% to 45%.
But Iowa is a caucus, not a primary. Caucuses are harder to poll, because instead of walking into a gym, casting a ballot, then walking out, caucuses involve sometimes-hours-long meetings in homes.
That favors a candidate with more enthusiastic supporters, meaning Sanders could cut into that five point lead, or even overcome it.
And in New Hampshire, Hillary is losing badly. She trails Sanders by 42% to his 56%. New Hampshire voters are largely.
If Clinton loses Iowa, that New Hampshire deficit will grow, meaning she will have to expend even more time and money to lock up the Democratic nomination.
