What would happen if trump were to issue an executive order banning abortions?

The Trojan condemn companies stock price would be off the chart.

Nothing different than now. Abortions would still be legal, and they would still happen.

Supreme Court ruled, he can't ban anything that is already protected.

Nothing.  Absolutely nothing.

It would be overturned in about half an hour.

Now let's get down to it---why do you think Trump would even try to outlaw abortion by executive order, after NOT doing that for over three years?

The courts would immediately block it, with good reason.  Executive orders have to be consistent with existing law.  They can't be used to create new law.

Supreme court throws trump out the window 

President cant go behind SC's back without getting shot by them

Congress is a different story 

It would get overturned.
