In places like the usa I don't think politicians should expect privacy or peace. They have so much power compared to the citizen and they so rarely further the interests of the general population in good faith.
Given how they treat you, it's best to abandon politeness (which only helps them further belittle your meaninglessness in their decision making) and put a crowd in front of their house, accost them at restaurants, and find other ways of reminding them how accessible and functionally answerable they are to the people they're supposed to serve.
