JOHN YANG:

The presidential candidates had a relatively low-key Memorial Day.

Hillary Clinton, who's closing in on the Democratic nomination, went back to the town she now calls home, Chappaqua, New York, to march in a local Memorial Day parade. Bernie Sanders spent today in California, the big prize of next Tuesday's primaries, and possibly his last stand. He marked the holiday in San Francisco, ahead of two events this evening in Oakland.

Republican Donald Trump stayed out of the public eye today. But as of this weekend, he can now count a former Republican governor as a third-party rival. Gary Johnson, who was once New Mexico's chief executive, ran for president as a Libertarian in 2012, winning just about 1 percent of the vote. On Sunday, the party made him its nominee once again, and picked another former Republican governor, William Weld of Massachusetts, to be his running mate.

For more on all this and the week ahead in politics, we have Amy Walter of The Cook Political Report and Tamara Keith of NPR.

So, Amy, Tam, reporters finally got their contested convention this weekend. The Libertarians went to two ballots. With both Donald Trump and Hillary Clinton, the two major party nominees, so unpopular, the Libertarians are hoping this is going be their big year.

Amy, what do you think?
