I'm working on composing letters to my state representatives for a contingency plan(city broadband). I read on reddit, that it might be more effective than directly contacting my federal representatives(I plan on doing that too.) I'll post my letters if there's any interest in them.
Yes. All elected politicians monitor public input on major issues.
It usually goes something like this:
1) Comcast lobbyist: Hey politican, we'll donate 10k to your campaign this year, and another 100k+ if it becomes a tight race, just promise you'll vote against net neutrality if that ever happens, ok?
1a) Comcast, that's a deal.
2) Office Aid: Hey politican, after the FCC announced today, our phones are ringing off the hooks. People are really upset about this Net Neutrality thing.
2a) Okay, poll our constituents, and figure out just how many votes I'll lose if I vote for this thing.
3) If the number of votes > than the amount of votes the politican thinks (s)he can buy via the lobbyist's money, they change their position.
So your letters greatly affect step 2. Of course, its less cut and dry than above. Democratic politicans by and large believe in NN. Republican politicans these days rarely do. And polls are expensive and slow, so sometimes step 2a is skipped entirely and the politican makes a gut call based on the amount of feedback they receive.
Would these letters be of any use?
