Woo hoo, let me be the first to base my prezdential campaign on a 2.5% cost "saving" minus a 5-10% MPG decrease for a grand total of yet another delusional action by a legislative body.

When the history of the late 20th and early 21st century is written, it will be known as the Upside Down Era or perhaps the Age of Insanity.
We take actions that hurt us while not taking actions that help us. We are ruled by lawyers and MBAs from the Ivy League who have absolutely no clue what they're doing.

E-10 is crap gas, if anyone honest ever runs the numbers an amazing discovery will be made: It works out to a negative, as 90% of legislative/congressional actions do.

Even George McGovern, a seriously simpleminded former senator and 1972 prez candidate who was probably responsible for driving more people from his party than anyone in history to that point, eventually discovered that there is a huge difference between sitting in a giant hall full of the self-important and actually trying to run a business.
His business went bankrupt, due to his own lack of management skills and the huge bureaucratic burden of regulations and red tape which he so self righteously voted for during his career as a Great Leader.

IMHO some people are taking bribes for this, no rational person would do it based on evidence.
