The law in question was likely intended to weed out just his type. And he doesn't like it.
"The political establishment does not allow non political insiders to run using this obscure law because most people don't know about it at all, and it's just unfair," Rust said.It seems rather undemocratic to prohibit candidates from running for office. If Rust is indeed a "phony", the proper way to prevent him from winning is to defeat him at the ballot box. Banning rival political parties and candidates is the kind of thing advocated by authoritarian regimes such as the Soviet Union and the Democrat Party.
I do think the primary votes in non-consecutive primaries seems “out there” to prohibit someone from running in a primary.
In this case, and knowing Rose Acre Farms’ products as I do, which have had a bible reference on them, I believe him. I can see voting for a friend in a primary, across your normal party line.
I would suggest he likely had decades of prior Republican party primaries he voted in.
The law seems excessive, but it may still stand, after judicial review.
