The guys at Power Line provide a link to a two-minute YouTube speech by Clinton Labor Secretary Robert Reich, now a prof at Berkeley. Reich argues why, from a lifelong Democrat's perspective, you should not vote for Ted Cruz; why Cruz is "worse" than Trump.
I listened to it, tiny Robert (< 5 ft.) is a good speaker and a fair cartoonist - it's entertaining. Reich convinced me if I had the opportunity to vote for Cruz, I certainly would do so.
Everything about Cruz that Reich detests, I like a lot. In fact, Cruz could use Reich's 2 minute lecture as a TV commercial, the Cruz website should link to it.
