Could Michael Schiavo still collect the 6.8 million that GlennBeck.com is offering?

I am thinking at this point that Mrs. Schiavo will die no matter what (she’s in renal failure ect). So Michael takes the 6.8 million dollar offer that Glenn Beck has made at his website (via people who say they will donate money). Wouldn’t this be a legally enforcable contract (I seem to remember something from business law about a legal case involving someone on the Johnny Carson show or the radio to pay money for something that was upheld by the courts). If I’m Mr. Schiavo I call first thing in the morning to take the offer knowing that Terri will still have her validated ticket for a final exit.
