Behind the scenes of Matt Bevin's loss in Kentucky's governor's race

• Bevin was telling people he would win — but throughout the campaign, sources in the Trump political orbit expressed concerns about the poor quality of Bevin’s operation and about his weaknesses in public opinion.
• The White House and Republican Party went all in to help Bevin: a Mike Pence bus tour, Trump trips, and major spending from national groups.

What they're saying: Trump said at a Kentucky rally on election eve: "[I]f you lose, they’re going to say, Trump suffered the greatest defeat in the history of the world."

• But sources involved in the unsuccessful effort to help Bevin pointed to the rest of the Kentucky ballot — every other statewide Republican candidate in Kentucky won by a comfortable margin — as consolation.
• They argued that Bevin was such a weak candidate that bigger 2020 lessons shouldn’t be drawn from his defeat.

Between the lines: Indeed, polling shows Bevin is the most unpopular governor in America, and other Kentucky results were solid for Republicans.

• As U.Va.'s Larry Sabato told Lawrence O'Donnell on MSNBC: "When you're a Republican running statewide in Kentucky, you have to try to lose. And Bevin tried for four years, and he succeeded."

The takeaway: Former Ohio Gov. John Kasich said on CNN that Beshear is a sign to Democrats nationally not to embrace plans like the Medicare for All and the Green New Deal, but to appeal to the middle and win as a moderate.

• Kasich said Kentucky's message to 2020 Dems is to pick somebody who most of the country can look at and say: "That's reasonable."
