NFO in Jax
I think you'd be hard pressed to find a government policy (conservative or liberal) that hasn't come from a seed of common/greater good.
Representing your community in the Senate or the House is supposed to be a two way street. Yes, you should be advocating for your locality when it comes to receiving federal aid, new projects, etc. But no, you shouldn't refuse to vote for something you know is in the national interest unless you get X number of dollars for some pet project in your district. That's extortion. Maybe you were going to vote for it anyways but wanted to get in a little something extra - that's even worse, given that we haven't balanced a federal budget in God knows how long. At some point during your term you might have to go back to your constituents and explain that you had to vote for something because it was for the good of the country as a whole, not just your small slice of wherever, and it wasn't appropriate to ask for a $50 million bridge when you are debating healthcare legislation (or military budgets, or social security, or whatever).
Blue collar vs white collar? Why can't we have both? It's a little absurd to assume that a community whose predominantly employment comes from farming or manufacturing is going to be adequately represented by a lawyer or a doctor. Where you came from and what you do isn't as important as how you purport yourself.
