Bloomberg is looking to purchase the election but not necessarily for himself. He can spend his dedicated campaign money pretty much as he desires and can direct it to actually support who he desires so long as there is some pretense that it is for his own campaigning. He has spent a LOT of money loading up the crucial Secretaries of State in the states and other things not to his own benefit and might easily push his own choice this way.
Thanks, that’s a reasonable explanation for Bloomies big spending on an election he’s got little if no chance of winning.
