Oh please! The legal battles to keep Kennedy off the ballot are simply how they’ll allow him to run in the states where he can hurt Trump and keep him from running in the states where he can hurt Biden.
He is pretty hardcore on the climate change stuff, has a history of being anti gun and publicly supported 3rd trimester abortions.
How many people who would vote for Trump are going to vote for a guy with those positions? He’ll hurt Biden more.
