From what I see on the ground, Harris is going to be knocked out of the race by New Hampshire primaries. She won't be able to compete with Biden and Bernie's money.
I predict a 4th place or lower finish in Iowa. The party hacks are solidly behind Biden as of now. I don't see it changing unless something really damaging comes out on him. Bernie is going to be enriching himself again. Doesn't care about actually winning because he knows he can't.
