Is There A Frist Flop In The House?

I see that Bill Frist has now come out in favor of stem cell research. Watch my head spin! His departure from the conclave headed by his fearless(or fearsome) leader, President Bush begs the question; is Mr. Frist going to run for President? For years Bill Frist's nose has been so far up George Bush's ass that if the President made a quick turn Frist would in up with a broken nose. What made Mr. Frist change his mind? Is this change of heart for the good of medical research or is it go gain support for a future Presidential run? And the Republicans said Senator Kerry was a flip-flopper!
