I think this would be a good move, but I fear the same as others. It will likely be an attack on GOP or just a political stunt. His executive orders he's using to bypass congress have all been campaign stunts so far. He knows his JAR is down and he's possibly in trouble and he's using his position (like most sitting presidents do in some way) to make a show.
All that said, this is a reasonable executive order imo and would get him some points with me. That assumes he does it to both parties and doesn't change his mind.
