(That this is repeat of a four year-old blogpost needs to be posted again is quite a disappointment. Trump has been a much better president than the country deserved, and he stepped up to the responsibilities quite a bit, but it's still pretty much a game of king-of-the-hill to him.)
Invite the top three third party candidates to the next one.
If they'll come.
(They might prefer to avoid the noise fight.)
If they would join the debate, the Donald couldn't just focus on Biden's perceived weaknesses.
Frankly, that the debate organizers have failed to go out of their way to invite the third party candidates again this year says something to me about the debate organizers' motivations and goals.
I said this last time, as well, but I'll say it again, also: a vote for third party candidate you can support is not a throwaway vote. Every vote for someone else tells them they're messing up. The major political parties need to get the message that they have long since ceased to represent any real constituency.
