Why does PA Gov. Rendell want to raise taxes when he is getting 3.5 billion tax dollars a year from casinos?

A friend of mine is an accounts payable clerk at a casino in Pennsylvania and writes a check to the Governor for $1,000,000.00 every single day for taxes! That's $365,000,000.00 a year from one casino and there are ten of them in the state... so far! That's $3,650,000,000.00 a year from the casinos that we never had before 2007 and now he wants to tax the money from drilling and increase the inheritance tax to 55%!!!!! Are you kidding me?????
