Polluters are fighting hard to get Keystone approved. The oil and gas industry pumped $53.1 million into last year's congressional campaigns--87 percent of which went to Republican candidates. Senate Majority Leader Mitch McConnell raked in $608,000 from the industry for his 2014 campaign, and now he is putting Keystone XL at the heart of his big polluter agenda. But this isn't just a battle over industry influence. This is a choice about the kind of nation we want to live in. Do we want to live in a country where expert reviews don't matter and industry profits trump our families' health? Do we want to lock ourselves into a fuel that generates 17 percent more climate change pollution than crude oil and makes our children more vulnerable to extreme weather? Or do we want something better?
