Fair question.
Trump is attacking DeSantis hard for supporting raising the social security retirement age to 70 and for cutting spending in social security and medicaid. There is no way those programs can go on spending at the rate they are. Trump is attacking DeSantis for making a hard, responsible choice.
Trump is also attacking DeSantis for supporting the national sales tax. He is again parroting Democrat lies that it raises taxes. If you read the screen as Trump bashes DeSantis, it says the truth that all other taxes are gone, but you'd have no idea listening to the lies in the attack.
So Trump supports having an income tax, which is the basis for endless government abuse against our privacy. Our tax system is flagrantly unconstitutional. Sure we passed an income tax, but government has no Constitutional right to send us demands to send our private information with no warrant.
Trump is also attacking DeSantis for Disney. Conservatives know what Disney is, again, not an appeal to them. I'm not voting Trump at this point
