Obama's Bull Market

And by the way, why hasn't Obama gotten any credit at all for the amazing bull market in stocks that has occurred during his administrations?

I mean, the value of all stocks, as measured by the Wilshire 5000, is up $9.2 trillion since Obama's first inaugural.

And up an amazing $2.7 trillion (18%) just since his reelection.

Many people are making huge amounts of money. If this happened under a Republican president we'd hear no end of it. So what's going on?

(By the way, stock market capitalization minus US debt has increased by $2.9 trillion since Obama first took office.)
