June 2 is the most important day of Obama's second term - Vox:
Adopt a rule that's too lenient, and the president will miss a unique
opportunity to make an impact on one of the most important issues
facing the world today. Adopt a rule that's too strict and he'll risk a
congressional backlash that could ultimately undermine the EPA's ability
to do anything. Republicans are sure to cry "overreach" no matter where
the administration comes down, but they would need Democratic defectors
to really change anything. Yet energy issues are highly regionalized,
and the risk of an anti-Obama backlash from Democrats representing
coal-dependent areas is real. Striking the right balance will be tough,
and regardless of what the rule looks like it will be some time before
we know whether Obama's done it.
But either way, make no mistake this — not the Keystone XL pipeline or congressional Benghazi hearings or clearly doomed transportation plans — is the political story to watch of our time.
