Let’s get real here. Roe vs Wade made abortion legal in 1973. Not one president since then has or could do anything about it. Reagan was a huge pro life guy, and he never once tried to have the law changed. Why? Because a president doesn’t have the power to legislate. The case would have to either come from the Congress as law, or someone would have to file a SC brief - and that also depends on whether or not the SC would hear the case. So, this is a hot button issue, but I assure you - Ted Cruz won’t be able to change anything in this regard either. Wise up!
Actually Roe left open the ability to regulate some abortions, such as late term abortions. It depends upon who gets appointed to the Supreme Court.
Trump has no idea who he would appoint, as he has not thought thru this or any other position.
