It’s Alabama! Moore would not lose the general. That’s why they’re so desperate to stop him, because if he wins the runoff, he’s the next US senator. Tuesday is it, and if Moore wins, it’s done.
The most the Establishment can do at that point is to get behind the democrat or run some independent candidate, or run Luther Strange as an independent (remember Murkowski in Alaska in 2010?).
When Moore wins the seat, he will be beholden to no one but the people. We need more candidates like that.
Whoever wins the 9/26 primary will likely be the next US Senator from Alabama. The dems don’t really have much of a chance at winning this seat.
The establishment - that includes Trump in this case - want Luther to win because he is a pliable politician and will wheel and deal. Moore is a principled stubborn conservative and will probably cause Trump and McConnell all sorts of problems.
