The Susan B. Anthony List observation that EOs can be rescinded at the president's whim is of course true. This particuar EO is also a nullity — presidents cannot enact laws, the Supreme Court has said they cannot impound funds that Congress allocates, and (as a friend points out) the line-item veto has been held unconstitutional, so they can't use executive orders to strike provisions in a bill. So this anti-abortion EO is blatant chicanery: if the pro-lifers purport to be satisfied by it, they are participating in a transparent fraud and selling out the pro-life cause.
Oh, Stupak will claim the “right wing court” stopped the president from fixing the bill.
I hope you are right. I am anticipating court challenges, we should find out tomorrow night when Mark comes on.
