Darrell - I haven't answered your question because the only answer to it is: Clinton *may* try to overturn it, but she won't be successful. Otherwise, it has no bearing on this election.
Ever hear the saying "past performance is not an indicator of future outcomes"?
Trump faces the same exact problem Obama did: mainstream republicans don't like him, which will make working with them problematic. Democrats hate him, and will probably enact an obstructionist strategy like the republicans did to Obama.
Unless Trump finds some way to work with both sides--better yet, unite them, which is highly unlikely considering the problems he's having uniting the republicans--he will have to resort to much of the same strategy as Obama, and executive orders will be the primary tool available to him.
Secondly, Darrell, you keep centering your statements around "not voting"; so far, ITL is the *only* one that has mentioned not voting.
As I said way back in post #11, one of the possible outcomes is that Trump will be a good, possibly even great president. And, as I also said, I'll publicly post my "yeah, y'all were right and I was wrong" if that outcome occurs.
