CONs are the means where states prohibit competition for their “pals”.
Pals, as in DONORS. It's not that hard to fix. Simply require that ALL political donations be ANONYMOUS. You can't sell influence if you don't know who is buying. Americans should be allowed to donate to any candidate or party they choose, in any amount they wish; that's FREEDOM. But selling and purchasing an outcome is BRIBERY, a CRIME. Lock 'em up!
