As terrible a decision as it was to foist Simmons this year, I disagree with it comes to self-funding candidates. The more of those we have, the less money the NRSC has to spend holding them above water. They can focus on other races.
Just tell the self-funders to screw off. They can use their limitless cash flow to fund PACs, donate to the NRSC, and donate to campaigns. They can't win themselves. But then why would they spend their money, you ask? Well, the Republicans in the Senate have done quite enough for the super-rich already right? You rub my back, I rub yours.
