"President Obama's policies have become part of the economy's problem."That's being quite kind. In fact, on January 2, 2009, with Bush still in office, the Dow finished at 9034. It began tumbling right after Obama's victory. Look at the graph above. On November 1 the Dow was at 9,500 but it went into free fall after that, erasing 1,000 points in two days.
There is not other reasonable conclusion. The dive the Dow has taken is entirely in reaction to the election of a tax and spend Liberal Democrat.
To date, the Dow is down 25%. There's nobody to blame but Obama and the fools who voted for him.
