alt Hacker NewsHonestly, I donate enough money to politicians to make them stand up and take notice when I email or call them and share my thoughts, which leads me to the conclusion that people in the middle and lower class are going to need to find ways to pool money in such a way that they can change their party politics. It's not that all politicians are completely motivated by money, but IMO you unfortunately have to aim at the lowest common denominator.
You can only donate $3500 to any politician. (legally, if you do something illegal and are not caught...). There are complex limits notice when you say something. (for a small city that limit will make them listen, but nothing national or even a large city)
What you can do is get out votes. People knocking on doors is still one of the largest drivers of votes so if you organize those systems they will listen to you.
