Since Kanye West says he'll run for president in 2020, do you think that Kanye West would cause a crazier election result if he is the Democratic nominee or if he ends up running as an independent (either from the start or after losing the nomination).
I would say Kanye would cause a greater change if he is the Democratic nominee, as it would mean he is the nominee of a major political party, whereas if he is an independent he will mostly get voted for as either a protest or joke vote.
Why would he run as a Democrat when he's a Trump supporter?
Trump supported many democrats and even gave $100,000 to the Clinton Foundation. It isn't impossible for Kanye to spin it, especially if Trump continues to displease non-whites.
