Sen. Barack Obama made two campus visits on Saturday as he campaigned in Wisconsin.

In the morning, the Illinois Democrat and presidential candidate spoke to a small group of students and administrators at Northcentral Technical College in Wausau.

“The economy is changing at a breathtaking pace, and we need different skills these days,” Mr. Obama said, according to the Wausau Daily Herald. “In a moment when people are finding it harder and harder to get ahead, it’s time to call upon our community colleges once again.”

Later in the day, according to the Milwaukee Journal Sentinel, he spoke to about 3,500 people at the University of Wisconsin at Eau Claire, where he talked about his plan to give college students $4,000 tuition credits. He has previously said that the credit would make community college “completely free” for most Americans.
