Old-timers still blame Pat Paulson for Humphrey's loss in 1968 and Jack Anderson for Carter losing in 1980. The people who voted for Bush and Dole blame H. Ross Perot for their losing. There are more 'legitimate' third-party candidates who played spoiler than Kayne West. Heck, 50,000 people voted for Jill Stein in Michigan in 2016. Considering that Clinton lost the state by roughly 11,000 votes, I'd say that played a role.
