This would require Mitt to flip BACK on abortion. It would require him to embrace socialism FULLY (as opposed to just snuggling up to it as he did in Massachusetts). It would be an excellent way for Mitt to slit his own throat and write his obituary with the Republican base.
Mitt will never do this. He has embraced Conservatism and needs to kick back and wait for 2012. He should take on some new challenge like saving some newspaper or some Hollywood Studio.
