To be fair that is complete BS without a hint of a shred of a notion of any connection with fact. ...
Well, you're both wrong. Bush did not mention cultivating saw grass in a SOTU speech, but that assertion is not complete BS.
In his 2006 SOTU, Bush said, "We'll also fund additional research in cutting-edge methods of producing ethanol, not just from corn, but from wood chips and stalks or switch grass."
In his 2007 SOTU, Bush said that he wanted to quintuple the use of ethanol and other alternative fuels by 2017. That same year he signed legislation that mandated that "the U.S. must use 36 billion gallons of renewable fuels per year by 2022, including 16 billion gallons of cellulosic biofuel."
Here's an interesting article on the topic. http://www.msnbc.msn.com/id/17398968/ns/us_news-environment/t/huge-federal-grants-cellulosic-ethanol/#.T0a4dnnvO8A It reports that the Bush Administration planned to spend $385 million on cellulosic ethanol. You can look up the 2006 and 2007 ethanol references in the SOTU yourself. Recent articles in the WSJ suggest that Bush's results from cellulosic alcohol spending was comparable to Obama's Solyndra performance.
Bush was a proponent of ethanol fuels, especially cellulosic ethanol. That assessment is neither conservative nor liberal. It's a simple fact.
