I pretty much gave up on voting for one of the major parties in terms of the presidency a long time ago. Since Bush v. Gore, I've voted 3rd party. Usually Libertarian...once I think for the Constitution Party candidate. I don't see that changing in this election. I don't know much about what 3rd party candidates will be running yet but they can't possibly be worse than Joe Biden and Donald Trump.
It's possible there will be a decent candidate in one of the primaries and I will vote in my designated primary. Just not expecting anything good to come of it.
