After living in the States a few years it's become clear that none of the 3rd parties are taken very seriously, and if you're not R you've gotta be D, and vice versa. For a country where I've met so many sharp and politically sophisticated folks, I think it's a bummer they have one binary choice when it comes to their national vote.
It's within the primary elections where you see the most interesting elections at times. Sometimes you'll get a challenger in a district where it makes sense, like when AOC took on an established classical liberal and flipped it, pushing the representation leftward while still being Democrat.
Mostly liberal, not leftist. (Even if they were, Bernie'd prove the point.)
The word "neoliberal" is also a problem. It is used negatively and aimed at a broad swath of center-left to center-right.
But in other countries, the people called "neoliberals" would be understood to be conservatives. Instead of using "n*liberals", we should be calling them "conservatives". Larry Summers, for example, is a conservative.
