If Bsuh vetoes this (which I believe he will) and there is no override, the Rats will scream about how there need to be more democrats in the House and Senate.
If he vetoes but there IS an override, many Republicans will lose the support of the pro-life voters, even those who did not support it.
Oh, wait, I thought of something: if Frist demands all of these changes and the House doesn't agree, perhaps it can be tied up in conference until Congress adjourns! Just like happened for several years with the Energy Bill!
I don't think they can craft a bill that pass both the Hosue and Senate, as well as override a veto. Nor can the House and Senate pass a bill that the President will sign.
Is Frist doing the President a favor by keeping him from having to veto a "popular" bill?
