That's one explanation for Ted Cruz's decision to endorse Donald Trump -- he may be yearning for a return to the national scene. Donald Trump called Cruz a liar, a Canadian, implied that his wife was unattractive and hinted that his father might have been linked to the assassination of Jack Kennedy. If Trump was 10 points behind Clinton, Cruz would be wise to sit out the election and say "I told you so." But if Trump narrowly loses to Clinton, then Cruz could be blamed for the defeat -- with repercussions for his own re-election effort in Texas. Worse, if Trump actually wins -- Cruz will be frozen out of GOP politics for four, maybe even eight years.
