What a question!

This one:

GOP Assault on Truth: Why Do Conservatives Pretend They Know More About Science Than Scientists?

Here's how it gets started:

Earlier this year, Rep. Fred Upton (R-Mich.) and Sen. James Inhofe (R-Okla.) introduced legislation “repealing the...[EPA’s] scientific finding that carbon dioxide and other heat-trapping gases are endangering human health and the environment.” That’s right, politicians voted to repeal a scientific finding. It failed in the Senate. But if Republicans were to take control of the White House and Senate, the bill would undoubtedly become law.

Really. Do go read the rest of it. It's an eye-opener.
