The religious far right just want abortion banned. But many in the conservative movement know that Americans while they favor restrictions and oversight, also see abortion as a viable medical procedure so they try to chip away at it bit by bit. The theocons are tired of waiting.
The Republicans had the White House, Congress and the Supreme Court and it bears mentioning they made little to to no progress on the religious right's drive to ban abortion. Because the Republicans know that to do that would be to deprive themselves of their most effective get-out-the-vote tool.
