A rational person would change their voting behavior if their views did not match with those of the people they keep voting for.
Did you read what I wrote carefully? I'll repeat it for you; no one representative exists that will align with a voter's worldview 100% of the time,
nor will that representative do everything you predict he/she will do. Such a utopia does NOT exist.
If the voters were concerned about the budget deficit and its impact on future generations, they would have not voted for the people who keep making it bigger.
Your simple-mindedness is cute, but ultimately not useful in the real world. People care about the deficit, but they care more about lots of things, depending on the voter; like jobs and the economy, healthcare, immigration, environment, etc. And they should care more about those things in the appropriate context.
Saying "I want a balanced budget" means nothing if you don't vote that way; either you don't really care about a balanced budget, or it is lower on your priorities than "gib me more free stuffs plz". Either way, the masses that keep voting in Democrats and Republicans are responsible for the budget mess.
Representatives that enact legislation are responsible, ultimately. Voters only have so much power or time.
One person cannot get legislation passed by himself. If he kept getting elected his constituency obviously thought he was doing a good job.
Oh the ironing. You just got finished telling me that voters are ultimately responsible for their rep's performance, yet you cannot hold Ron Paul's feet to the fire for never in his life getting a bill signed into law. I'm sorry you do not realize the hypocrisy here or the failure of a legislator like Ron Paul to perform his most basic of legislating duties.
I know this is hard for some people to understand, but the government does not need to be constantly passing new laws to be doing a good job. More laws usually creates problems, rather than solving the issues they were intended to fix.
Another simple-minded world view that isn't practically useful to people who want to get stuff done.
