I too have been thinking but not wanting to believe this, hoping against hope it wasn't true.
The LOVE of money (not the money itself) is the root of all evil. (and you can look that up!)
Wealthy people don't like to contribute to grassroots campaigns without a political consultant in control so the candidate won't lose control and the peons be havin big parties and barbeeques with their contributions.
They generally don't trust righteous conservative candidates or populist candidates unless a political pro has a short leash on the campaign treasurer.
They're also afraid of being turned on by the conservative candidate after elected should righteous principles in public policy become involved if you know what I mean!!!
