Is it easier for the general population to sway the voting of their democrat representatives towards healthcare and education reform or is it easier to sway the Republican reps? What about primaries, if your rep stubbornly refused to support their constituents desire for healthcare and education, are there democrat candidates that could be more focused on those issues? Are there Republican candidates?
You kind of need to work with the system you have until you can change it. Either you find the revolution, join it and force the change through violence, or you work in the system and push the reps you have to make it what you want it to be. There are no third party reps and won't be until you switch to a less archaic electoral system which won't happen without revolution or reps that understand it and see the value.
