Take a Memo:
I don't really think the issue is making money less important of an influence on politicians , but rather recognizing it is a factor which tanslates into power and hence puting a limit on it.
And here is where I think you are wrong. money translates to power when you have people motivated by money instead of character and integrity. An elected representative has tremendous power already, but he/she is supposed to be persons of integrity and good character.
The only "fair" limit you can put on campaign finance is to disallow it all. By trying to hunt and peck around, you are disenfranchising people and their right to political free speech while making others more influential and important.
