Will third parties get even more irrelevant?

[Grassroots]

There are rifts growing in both parties. On the left, a split is growing between progressives and moderate democrats. On the right, a split is growing between more socially liberal "libertarian" types and nationalist/populist conservatives (Trump has covered this up but he won't be around forever).

We have already seen the divisions, they are growing. The "and bust" mentality is only going to grow. Idealism is the dominant mindset in American politics going forward.

IMO, it's not a question of if we become a multi-party system sometime soon, but when. I say sometime later this decade.
