Under an expanded US House of Representatives, wouldn't current campaign finance laws still be a problem?
Well, duh.
But there is a simple solution.
Your man or woman in Congress should represent YOU, not Freedom Works, The Club for Growth, People for the American Way, Planned Parenthood or any other national organization, including his or her own political party. It is not right that the RNC collects contributions for Kevin Yoder in Kansas-3 and spends them on the US House race of Maria Elvira Salazar in Florida-27.
Your representative should represent YOU, and the money that elects him or her should represent you, too, and therefore all campaign contributions must come from his or her congressional district, from people and businesses actually domiciled within district boundaries. That's it. No other limits.
Nancy Pelosi can raise all the money she wants from tuna companies domiciled in her district who exploit workers on Pacific islands. Let the actual residents of her (much reduced in size) district decide if they're still OK with that. And Fred Upton of Whirlpool fortune fame in Michigan can find out for himself if his much reduced number of constituents are OK with making their lightbulbs more expensive or unobtainable.
Power to the people.
