If I had to vote for Sam Nunn of 1975 and Linc Chafee of 2005, I'd vote Democrat.
So would I. But the dem party of 1975 was such a different party than it is today. I tended to vote more for the person back then; now I tend to vote more along party lines. Usually I want to vote for the Republican candidate, but if I don't, I weigh the character of the dem candidate against the Republican party. Yet, I do not always like the direction of the Republicans either.
