It's The Economy (Again), Stupid

Presidents are seldom responsible for the performance of the stock markets, but this one is an exception.  Market prices are always roughly reflect the present value of future income streams, the expectation of which ratcheted upward last November with the election of a President who promised, and appears to be delivering, lower taxes and regulation for businesses.  Economic growth is driven by corporate profits and the reinvestment that devolves from those profits. We have experienced this twice before when President Kennedy and President Reagan cut tax rates. Democrats -- stuck with their Keynesian assumptions -- seem not to have learned this lesson. Or don't want to. It appears that they will come out in unanimous opposition to lower taxes and higher growth. A rather peculiar platform to run on.  Maybe they ought to remember what James Carville said during the Clinton years -- it's the economy, stupid.
