Thank you for your post –
I must respectfully disagree as someone who has worked in a senior political office and dealt with our state’s congressional delegation on a regular basis.
Yes, lobbying is very important – However, in my experience, well informed public pressure is more important.
The impact of a detailed letter demonstrates to the politician that he/she will be unable to spin their position... and thus applies greater pressure.
With that said, there certainly are greedy politicians who ignore constituents and are primarily motived by the lobbyist (and the related campaign contributions).
Don't bother running away ... you'll only die tired.
