Likewise, lets do some more detailing on your points.

1. Obama didn't just vote in favor of nuclear. The nuclear industry is his 4th largest contributer.
(BTW, your attempt to label nuclear as an alternative fuel is inaccurate but very Bush-like. Kind of like Peace-keeping missions in Iraq.)

2. Obama did contribute to Leiberman, but Obama also went out and campaigned for Leiberman. This extra mile to defeat Lamont could only come from a politician that is firmly entrenched in the status quo. Who's Leadership PAC (a gaping loophole for crooked, powerful contributers) is and has been one of the best funded for years.

I didn't bring up corn-you did. (No surprise from a Midwestern Senator. Kind of like building bridges in Alaska.) Corn-based fuels require nearly as much petroleum energy to produce as it ultimately provides. When one considers the additional resources necessary and the effect this has on corn food prices, particularly to the dietary needs of poor Latin-American countries, the net effect is devastating. Of course this is great for giant Hillary/Obama/Bush supporters like ADM.
Coal gasification, as well as corn based fuels are great for the powers that be but a sad solution for the publics health and pocketbooks.

This is no time to time to be supporting compromised candidates just because of their race, gender or oratory skills and mellow voice. The stakes are way too high.
