If Republicans control government, it loses all ability to regulate, and the country goes back to looking like this.

How can this be? Republicans have introduced

the REINS Act (Regulations from the Executive in Need of Scrutiny). This law would require that every “economically significant” federal regulation (one that has an annual impact of $100 million or more) be affirmatively approved by Congress. Again: no rule would go into effect until it has been voted through by both houses of Congress and signed by the president. If a regulation is not voted on within seventy legislative working days of being sent to Congress, it is “tabled.” That is, it dies.

That’s from an article in The Washington Monthly by David Roberts. He goes on to say

It would subject fifty to a hundred regulations a year to the partisanship, rancor, and gridlock of Congress. Every rule would be a new opportunity for lobbying and industry influence. Worse, legal observers say the bill does not clearly prohibit a filibuster in the Senate, raising the possibility that a determined minority of forty senators could effectively shut down federal rule making. REINS would not overturn the Clean Air Act or shutter the EPA, but it would end forward momentum in environmental law, freezing it in place.

Friends don’t let friends vote for Republicans.
