And that's exactly the problem that has been festering since at least McCain-Feingold's stupid Campaign Finance Reform that went in the wrong direction — restricting, instead of liberalizing campaign donations — and that has not gone away with the Citizens United decision, it just allowed creation of SuperPACs but it is nowhere near of removing the advantage of very rich self-funding candidates who can "loan" money to their campaigns in primaries and suffocate most worthy but cash-strapped candidates, particularly with many candidates running and donations being spread among them.
Look at the one-richer-than-the-other candidates Republicans had recently — McCain, Romney, now almost/possibly Trump? What's the next stop — "successful, self-made, many times richer than Trump, one-time-Republican" Michael Bloomberg? Or better yet, Hillary Clinton donor Warren Buffett, who is self-made, has 15-20 times more humility than Trump despite being 15-20 times richer — they were worth about the same $40M in 1974 — doesn't sue or gets sued by many people and created $billions of wealth for other people, instead of destroying $billions of other people's money?)
Newt Gingrich was right "on the money" in 2014 about the checkbook politics and what needs to be done:
