Why Hillary's Embracing Bernie

It was only a tweet, but one could detect a certain jubilation in Hillary Clinton’s voice as she “welcomed” Vermont Sen. Bernie Sanders—the senator so far to the left he’s not even a registered Democrat—into the presidential race. Clinton tweeted, "I agree with Bernie. Focus must be on helping America's middle class." Why is Hillary happy? First of all, Bernie has no chance of winning the Democratic nomination, whereas Elizabeth Warren might actually have a shot. Above all, the weakness of Bernie Sanders and her other likely challengers virtually ensures that she will not be forced to adopt policies so progressive that her cautious campaign team fears could cost her the election in November.
