Independent sounds a little lonely. I like moderate, although usually refer to myself as a semi-dem.
Have really grown fond of the moniker commie pinko though... reminds me of women in "dungarees" and checkered shirts.
The one thing that I think defines an independent (my preferred term) or moderate is an unwillingness to either believe or spew party line rhetoric. Look at this board for example, are there not posters on here that will defend their parties view no matter what? Even in the face of overwhelming evidence? I'm not singling anyone out because both Democrats and Republicans do it. The current Republican Administration is just such a disgrace that the conservatives are the ones showing it the most right now but when there is a Democratic Administration in the White House the Liberals will be doing the same thing.
To me it makes more sense to vote by your opinion of individual politicians than it does to vote by party lines. It's the same with political views, why not look at each issue independently rather than simply following what a party line says?
I would bet if everyone did that the majority of people would find that they're fiscal conservatives and socially liberal.
