* focus locally; getting invoked with local politics by supporting local candidates with your time and effort - the state department runs programs to talk to city and state officials concerning foreign policy matters and city’s and local governments can create pressure on federal representatives from those states.
* vote with your wallet; boycotts and divestments are tools ordinary people have to effect conglomerates. Ensure your retirement money is not invested with companies engaging with the political ideas you do not agree with
* protest; attending in person events shows leaders numbers and images that are harder to ignore than their consultants’ polling data.
I've done all of those and while I think they are important i believe it's most important to let politicians know, otherwise they rely too much on money.
Pointing that whatever people think they are doing is not working does not mean we have to propose a solution. I'd suggest revolution, but that won't ever happen in the US.
