The second reason I think the proposed legislation is unrealistic is that the Senate won't approve the legislation.

Most of them think environmental laws should only come from the states and not the federal government.

Which, again makes my vote politically risky without any actual benefits for the environment.

Yeah, if the Senate doesn't approve, you'll have to have the Supreme Court approve of it and they're notoriously tough!

Yeah, both sides of Congress, the Senate and the House of Representatives, must pass all pieces of federal legislation.
