Would the US be better off with a multi-party system?

[IceAgeComing]

Multi-Party system? Not in our first-post-the-post system, our Presidential republic. We would need a Parliamentary system to have relevant third, forth, and fifth Parties. A fifth Party could easily be the "Knights Party", the political arm of the KKK. Does anyone want a coalition involving the KKK or the Communists? 

No, I don't want a KKK or communist coalition. Golden Dawn has a coalition in Greece.

...Golden Dawn isn't in government in Greece.  Sure they have way, way too much power (although they've stagnated in recent years thankfully); but they are nowhere near government and hopefully never will be.

It would be more like a Socialist-Communist coalition,a Labor Party-Communist coalition or even a Center Left-Labor Party-Socialist-Communist coalition in a multi-party Republic.

you are thinking too much about israel/italy.

such fates can easily be avoided.

and do you really think, the official alt-right-party would have gotten as many vote as "the party not really rejecting the alt-right but not alt-right"?

No, but the center-right party would have required the alt-right party's support to govern, so in the end the result would not have been all that different.

If the alt-right party grew too large and stayed too extreme, and the Repubs didn't win a large enough percentage but still had a plurality, they would either govern in confidence-and-supply or a grand coalition.
