It would be great if a strong and moderate 3rd party could be developed that cared about the people of the US and real issues that real people deal-with. There isn't too much difference between either party IMO; there are a few exceptions, but generally I just can't get over the gnawing feeling that members of both parties are more concerned with staying in Washington than they are about any particular issue, or representing the people...which is too bad. As near as I can tell, the only thing that Democrats stand-for is being anti-Republican, and the only thing that Republicans stand-for is maintaining their power-base.
There are social issues that are crying-out for attention that neither party is willing to address because both parties come from the privileged class and it's in both parties interest to maintain things as they are while creating the illusion of getting something accomplished. For example education. Do you think leaders of either party and their friends send their kids to public schools? They don't, they go to prep-schools to the tune of $30-40K per year. That's where leaders from both parties are groomed.
Does anyone think it's strange that Bush Senior and Bill Clinton have been paling around together? (one thing about Clinton, regardless of whether you agree with his politics or not, is that he was an exception and was self-made)
It's interesting that the Democrats are the ones championing civil liberty issues right now, and are the only hope of examining the effects of things like the Patriot Act, while the Republicans are the only hope for maintaining private gun ownership rights.
Both parties benefit from maintaining a close balance of power because neither party would know what to do if they didn't have the other party to blame/villainize for their short fallings. Regardless, decisions that affect the United States aren't made in Washington, they're made over a round of gulf and $500 lunches at private clubs by old pals that were on the rowing team together back in prep school.
