Excellent piece. This is why Big Business and the Billionaire clubs like Democrats, in a nutshell.
Actually it's why big businesses prefer country club Republicans such as GWB and his father. Reagan was an exception in that small and new businesses were a key part of his economic recovery program. Our current tax cut includes breaks for small businesses (thank goodness), but it's not something that GWB pushed for. He just signs whatever comes out of Congress.
Historically, the stock market actually does better under Rat presidents. As noted, Reagan was the exception.
