In 1992, during the Democratic Primaries, Gerry Brown stated in his run for President he would accept only $100 donations for his campaign.
He raised a considerable amount of money and came in third in the primaries. He received matching government funds during those primaries. He didn't win that nomination, but, he was an wonderful example of how average Americans believe in HONEST candidates.
He is again Governor Brown of California. I am confident any candidate needing insight on how to raise campaign contributions can reach him for advice.
Oh, yeah.
There is another Democrat that FIRST asks his 'grassroots' for support through contributions they can send him. He raised nearly $700,000 alone from his grassroots this year. That HONEST Democrat is President Barak Obama. I believe he did that through internet requests and keeping in touch on a regular basis to update all those that support him. Interesting guy, the President.
Good luck.
