My guess is that with the exception of the recently elected congresspersons practically all the old establishment have dirty political laundry which they don’t want exposed insofar as any funny funds from organizations such as the multitude of those funded by people like Soros. It is no secret that all powered politicians are such because of being bought.
Believe it or not I actually found something that Open Society Institute gives money to that isn’t radical left.
It’s a magazine that brings news out of North Korea, I guess Soros will fund anything meant to undermine a country, lol. Maybe funding this is an accident, wouldn’t doubt it.
