I for one will be very unhappy if it doesn't play out that way. That's what brought me and millions of others into the voting booth in Nov 2000 and again in Nov 2004. If the Prez and Congress don't deliver the goods on this issue and pro-life, I'll be very much less inclined to do grass roots work for the GOP in 2008. Many in my church feel the same. We're owed for our work and we expect payment.
While I agree that it should be that way, it is just nearly impossible that around 50 years of precendent will be thrown out with automatically. It will be very difficult to undo what judges have wrought for half a century.
