I don’t know what could have been more straight than my only reply to the OP
“There were no primaries in the USSR, there was one party.
I would vote against any candidate for public office in a non-theocracy who promised yeshiva funding, or Catholic school funding or any other money for religious education at taxpayers expense, and YES, I oppose school vouchers.”
The OP posed a physical impossibility To vote for a dead non-US citizen who was also a non-member of the Democrat Party in a primary. I pointed out the physical impossibility and clarified that I’d vote against politicians wanting to use public funds for religious education.
