I consider third parties running in Presidential elections to be joke candidacies but what you’re saying is just the whining of whoever lost the election that was influenced by third party voters. Would have been the same result if the third party voters didn’t vote btw.
In the US electoral system, voting third party doesn't send a signal. It throws away your vote. Let's take a look at what voting third party has done.
1. Voting for Nader led to Bush Jr. winning the presidency in 2000. 2. Voting for Jill Stein led to the first Trump presidency in 2016.
So you got that going for you.
