Former President Bill Clinton was in Flint Monday campaigning for his wife Hillary.

"This election will be decided by if we choose answers or anger," said Bill Clinton. "Whether we think we're all in this together, or it's us versus them. And whether we think we can be safest in the world, with walls or bridges."

Michigan could be the key to the White House, which is why both campaigns have been stopping here so often. Clinton was in Saginaw earlier today and is now making some unscheduled stops around the area,

He spoke before a crowd of about 500 people today as he touched on health care, debt-free college, taxes, enforcement of trade agreements, immigration and his main message - choosing bridges over walls.

"I'm going to tell you why you should be for Hillary," Clinton said. "You already know why you should be against the other guy. I am going to tell you what is in it for you. I have this crazy and apparently old-fashioned idea that elections ought to be carried out based on who is going to do the best job for you."

The big question is whether he can reach the undecided voters with Election Day just a month away.
