Terri Schiavo's feeding tube has once again been removed, and you can bet your bottom dollar that a lot of people are using this for political grandstanding. I would have to iimagine that it is the Congressional Republicans who are leading the charge as in line with the wishes of their pro-life constituents.
Now for the hyperbole. If any issue of the day were to create a Constitutional crisis, this would be the one. The judge in the case is taking a clear line that is not at all to the liking of the majority in congress. I see the potential for someone, quite possibly fed up judicial activism, to... and here I run out of steam. If it were the president who was pushing to keep her alive, then there is the potential for law enforcement to become involved. That almost happened with Jeb Bush, governor of Florida, who rushed through a bill to make disconnecting the feeding tube illegal, only to have it struck down by the Florida high court. The next few days are going to be interesting to see how well the concept of separation of powers holds up.
