And since Hillary is probably the most risk-averse person imaginable I'll say she chooses the safest pick of all for her running mate, Sen. Tim Kaine of Virginia. (He's currently second or third on most betting websites and a bona fide Boring Old White Guy.) Elizabeth Warren may be too much of a reach, both personally and politically, Julian Castro doesn't have the experience (and, let's face it, looks too darn young) and Sherrod Brown, like Warren, would be replaced at least temporarily by a Republican governor.
So I'll say it's Clinton/Kaine in a walk in November. And Kaine's replacement in the U. S. Senate? Why not Creigh Deeds?
* Don't most presidential elections? The last risky choice that I can think of was Reagan. And with a weak economy and hostages in Iran, Carter was very unpopular. Right now Obama's approval ratings are over 50 percent and the economy is still expanding, if less so than last year.
