Donate the maximum amount legally allowed (as an individual).
Tell the Member that you would like to become a bundler.
(A bundler is a person or small group of people who pool or aggregate contributions "from the community" and then deliver them in one lump sum to a political campaign).
Once you have raised a sizeable amount, deliver the money to the Senator so they can use it wisely. In turn, ~~trade stock options based on insider information to the tune of millions~~, be super glad that you helped the democratic process!
And dark money!
