I will start things off:
Mitt Romney made a case for his experience, and in doing so, compared his economic and political experience to Hillary Clinton. In doing so, he said "I can't wait to debate with Hillary Clinton, because I have done it, and she's only talked about it. " I couldn't agree with him more. I look forward to their debates.
John McCain made a ridiculous comment about oil companies: When asked if he would require oil companies to spend a percentage of their profits on new energy technology, he ultimately said "NO", but first he said "I would hope that these companies would reinvest in new technologies like nuclear power." Has he forgotten what that industry has done for the past 20 years? In my opinion, the oil industry HAS NO INTEREST IN NEW ENERGY TECHNOLOGIES. They are interested in selling oil for a profit. Period. Why would they ever choose to give away money to actually decrease their profits? The oil industry is squashing potential for nuclear. The oil industry is lobbying Washington to keep fuel efficiency requirements for cars and trucks as low as possible. The oil industry is buying up patents on high efficiency / high output batteries in order to prevent them from being used in automobiles! It is obvious who McCain has in his back pocket...............THE OIL INDUSTRY.
I should also add that I got a good chuckle out of Mitt Romney's quote about the series of republican debates : "These debates are like Law and Order : There's a huge cast, it seems to go on and on, and Fred Thompson shows up at the end".
