8 a.m. - A loyalty test for Democrats?

The party's latest presidential debate is Sunday night at 9 p.m. in Flint, Michigan, and it runs two hours. That's the same start time as the finale episode of public television's "Downton Abbey."

7:50 a.m. - The busy weekend in the 2016 presidential race continues with two more contests Sunday and a Democratic debate.

Republicans in Puerto Rico are voting in the party primary. Democrats in Maine are holding their caucuses. And Democratic candidates Hillary Clinton and Bernie Sanders are taking the debate stage on Sunday night in Flint, Michigan.

Saturday's results: Wins for Republican front-runner Donald Trump in Louisiana and Kentucky, and for rival Ted Cruz in Maine and Kansas. Marco Rubio was shut out and is pinning his hopes on winning his home state of Florida on March 15.

Sanders took Kansas and Nebraska, and Clinton prevailed in Louisiana.

There was no serious erosion in the delegate lead for either Trump or Clinton.
