DngrRuss, I don't know if I agree with the sentiment of your thought. I'm going to offer two of my own thoughts.
1 - The Republican Party has usurped "Moral Values" - whatever the hell that means - and that was and is a mistake.
2 - People who will reach the pinnacle of public service will be ego driven people, independent of their political leanings, and personal foibles.
The Republican Party has gone out of their way to associate themselves with the remnents of the "Moral Majority". On subjects from adult consensual sexual relationships, to homosexual marriage, to Stem Cell Research, to Intact Dilation and extraction, to permanent vegatative state; they have proclaimed there can be no difference from their position, else you are immoral. Certainly, I do not think all Republicans believe this stuff, but when the President interrupts his vacation to sign into law a bill for the benefit of Terri Schiavo, it demonstrates either what he believes, or what he thinks his voters need to see him believe. And from those positions, there is little discussion or negotiation that is acceptable.
Courage of your convictions is very good thing .... but, if you stand on those convictions, be sure never to waiver. Because that will get you in trouble. You can't be the party of law and order with people like Robert Ney, Duke Cunningham, Bob Taft and James Tobin pleading guilty for their actions.
People who reach Congress and Statewide office, are driven people. Once in place, they have staff to arrange everything for them. Having many people around you to serve has to create an air of arrogance, I think. I recently heard Joe Scarborough (no alter boy himself) talk about not even realizing he hadn't driven a car during his time in Congress. That sets the stage for things such as Gary Hart getting caught with a woman, not his wife, on a boat called Risky Business, after telling the Press to follow him if they don't believe he isn't faithful to his wife.
No one is immune from that thought pattern, regardless of political party.
This Republican Majority, however, has gone out of its way to set itself up as a permanent Republican Majority, through redistricting, and proceedural changes in the house that strip the opposition party of any power sharing responsibility. They made their bed, now they must lie in it.
OK, enough for now.
