The Note: Alabama Senate race deepens GOP divide

— -- THE TAKE with ABC News' Rick Klein

It's a given that President Trump won't blame himself if Alabama voters go the way he doesn't want today. He will probably declare victory anyway, whether or not he knows the winning candidate's first name. The question becomes what he does with a loss. This endorsement was more about policy than politics – an unusual move in that it had the president keeping an eye on governing, not tending his base. If Roy Moore wins the GOP nomination for the Senate seat, it's likely to further fray Trump's relationship with Senate Majority Leader Mitch McConnell – both because McConnell went all-in to save Sen. Luther Strange, and because Moore is in line to become one more senator the leader can't control. In a week of more legislative failures, punctuated by strike three on health care, Trump will become more prone to looking inward for what he can define as victories. Steve Bannon's explanation for supporting Moore over the Trump-backed Strange is instructive: "We did not come here to defy Donald Trump," Bannon said last night. "We came here to praise and honor him."

SESSIONS' SPEECH ON FREE SPEECH

The irony is lost on no one, especially not the faculty at the Georgetown Law Center, where Attorney General Jeff Sessions is slated to speak today on free speech. The attorney general is expected to argue that conservative voices are under attack and are at risk of being silenced by liberal teachers and student bodies. He will likely say it is wrong for college campuses to limit who can speak and where. His remarks, of course, will come just days after the president lobbed expletives at American athletes engaged in non-violent protests, and suggested they should be fired for acts of expression. It's unfortunate timing for Sessions, who could come off as suggesting that, in the eyes of this administration, some Americans are more free to speak than others. The implication is that this White House is prioritizing the First Amendment rights of those who agree politically. Ahead of his remarks, more than 30 Georgetown professors felt compelled to write about what they see as the attorney general's "hypocrisy," citing past Justice Department efforts to prosecute dissenters: "This kind of government chilling of speech is precisely what the First Amendment to the United States Constitution is meant to prevent," ABC News' MaryAlice Parks notes.

What to know about the Republican runoff for Jeff Sessions' Senate seat. Today, Alabama Republicans will vote in a primary runoff for the Senate seat previously occupied by Attorney General Jeff Sessions.
