Alabama picked the winners.

Donald J. Trump did not lose a single Alabama county to his closest rivals, Ted Cruz and Ben Carson, during the Republican primary on March 1.

Trump's worst showing that day was in Lee County around Auburn, where he still beat all of his opponents and claimed more than 30 percent of the GOP vote.

Hillary Clinton also swept Alabama, easily beating Bernie Sanders in every single county during the March primary.

Sanders came closest in Blount County, outside Birmingham, where he claimed 38 percent of the Democratic ballots. But many rural counties were solidly for Clinton. Sanders didn't crack 10 percent in much of the Black Belt.

Now that the primaries are winding down, and Clinton and Trump are headed toward the nominations, what is the county-by-county outlook for November?

Alabama as whole remains red. No surprise there. But in the primary Clinton out-polled Trump in 26 of the state's 67 counties. Most were small and rural, although she also earned more votes than Trump in Jefferson, the state's largest county, and in Montgomery.

Some of that was due to the busy GOP field. Should all of those GOP voters now unite behind Trump, and all of the Sanders supporters swing behind Clinton, that would leave Trump with 463,000 more votes than Clinton -- an unbridgeable gulf in a state of fewer than 5 million people.

When looking at total vote by party, only 16 counties saw more blue than red in March.
