In the long term this decision is better for regulation. Anything that a president gets the EPA to do can be undone by a president that disagrees with them.

In the long term this decision is better for regulation. Anything that a president gets the EPA to do can be undone by a president that disagrees with them. By it's nature the presidency is unitary - so any president will find it difficult to compromise with itself. Congress on the other hand - even the House though less so then the Senate - requires compromise, requires some degree of buy in from all parties involved. This means less sweeping action - but anything that does get done will have advantages to a larger majority. Those supporting it will have an interest in it continuing because they will have been given something for their vote.
