Ben Sasse is a senator from Nebraska.
What he's missing is that the nation is split, almost evenly. It has also turned into a "Vetocracy," in part by design of the Framers. Almost anyone sufficiently unhappy with a policy can delay it going into effect; and grind it into inefficiency, if not totally halt it.
The fault is not with the party system. Other nations use different party systems, and have the same issues -- or worse.
There is no way to eliminate the party system. If nothing else, demanding we do so would violate the freedom of association.
I find it slightly ridiculous that he basically says "we have to indoctrinate our children to think of America the same way I do," and that a failure to do so is an existential threat.
I find it odd that he fails to understand that his party's voters nominated Trump.
He utterly fails to understand what's involved in the job of the Presidency. It can't possibly be limited to 3 or 4 things. That is not how the job is structured.
The idea that a president could get much done in a single term is absurd -- as evidenced by his own party's refusal to even consider a SCOTUS nominee nearly a year before Obama's term ends.
IIRC Sasse is publicly saying "we need a 3rd party candidate, but I'm not gonna do it." Meanwhile, it's too late for 3rd party candidates. E.g. to get on the ballot in Texas, you'd need 79,000 signatures by Monday, May 10th. (

And of course, if the GOP was able to select a half-way decent candidate out of the EIGHTEEN who ran for the nomination, he wouldn't be whining as much; he'd likely line up behind the candidate.
At the risk of being crude, the GOP voters have handed the GOP elites a **** sandwich. I guess I can't blame the guy for not wanting to eat it, but it's too late. They had plenty of chances to pick someone else.
