Sanders told MLive and The Grand Rapids Free Press, two Michigan publications, on Saturday that the GOP primary is falling to new depths of immaturity.

Rubio recently implied that Trump had wet himself before a debate and made insinuations about the size of his hands.
The billionaire at Thursday's debate insisted he is well-endowed — rounding out a new low point in modern political decorum.
"I think that is not what the American people want. The American people know we have some serious problems and they want to hear some serious solutions to those problems, not vicious personal attacks," Sanders said Saturday.
Michigan has 147 delegates at stake on Tuesday on the Democratic side.
Sanders attended a rally Friday in Grand Valley.

He lags Clinton by 634 delegates, but much of the gap is due to her commanding lead among superdelegates, who are not bound to vote for the former first lady at the party's convention. She has 458 party officials in her column compared to Sanders’s 22.
Sanders emphasized to the Michigan publications his difference with the former secretary of State over trade.
"Secretary Clinton and I have very profound differences," he said, according to MLive. "I was on picket lines with union members in opposition to NAFTA. I knew then it would be a disaster for American workers.
"These trade agreements have cost us millions of good-paying jobs all over this country, and the Midwest, Detroit, Illinois, Ohio have been especially hard-hit with these disastrous trade agreements. I have vigorously opposed them. Hillary Clinton has supported them. I stood up to corporate America. She worked with corporate America," he added.
Sanders has also stressed the need to crack down on Wall Street firms, which traditionally have supported Clinton, who formerly represented the financial services industry as the junior senator from New York.
Income inequality and the need to expand Social Security have been two other go-to issues for Sanders.
