If the 17th were repealed Montana sure wouldn’t be sending liberals to the Senate. But I would want a few other changes too - (1) term limits, (2) barring sitting congressmen and candidates from accepting $$ from anyone who resides outside their district or state, and (3) barring them from accepting ANY $$ from ANYONE while in office.
This way, Hollywood couldn’t pour money into House and Senate races anywhere outside California, and congressmen wouldn’t be bought off by lobbyists and special interest groups.
I’ll make a not of your wishes...
