What's a good label for the right-wing billionaires (Kochs, Murdochs, etc.) fueling the insane wing of the Republican party?
"Billionaire" isn't precise.
"Right-wing billionaire"? I'm not sure even "right-wing" fits, because there's a highly variable mixture of Racism and "my single-issue is don't tax/regulate my business".....
Kleptocrat? Oligarch? Plutocrat?
