Yes, this is an excellent site, and this is the site where I go to evaluate what they say versus how they vote.
Obama gets some stuff right as they all do. But mostly he is a pure liberal with obvious socialist leanings, and he doesn't always vote as he talks. He promises to 'reinstate' (as if it ever existed) 'paygo' when he is President, and yet his voting record shows little conviction toward that end.
Still, he is certainly not more dishonest than any other candidates and therefore scores okay on the honesty meter. So if you lean far left and want a president who will support most modern liberal causes/issues, he could very well be your man.
Hillary by contrast seems to have no strong convictions about much of anything and I think will be whomever she thinks she needs to be to look good.
So if you don't lean so far left, but realize we are going to have a Democrat president, which do you choose? The one with no strength of conviction so you can't be sure what you'll get? Or the one with strength of conviction who supports a lot of things that you oppose?
McCain has abandoned the conservative ship too many times for me to fully trust him, but then so have Giuliani and Romney but at least they both were governing very liberal states at the time. Huckabee to me may be the most dangerous of the front runners so far as standing firm on issues important to me. Thompson's voting record is pretty good and he talks a good game, but I am not sure he is sufficiently personally appealing to beat either Obama or Clinton. Duncan Hunter, with solid gold conservative credentials, never had a chance.
Still it is turning out to be an interesting election, and overall we do seem to have a pretty good group to choose from. Since we can't have Superman, I hope we pick the best from the lot.
