Penn State University joins Operation Yellow Elephant

Here's what happened at a Casey event at Penn State University:

Chairman Todd Taylor and fellow College Republicans were present at the Casey rally to show their support for his opponent, by holding Santorum campaign signs at the end of the event.

College Democrats press secretary Eliot Schmidt said he was happy the group saved the protest until the end.

"I appreciate that they were so respectful and hopefully we will be able to continue this trend," Schmidt said.

However, other Casey supporters were not as receptive to the College Republican's presence.

After the event the College Republicans were met with comments such as, "Why aren't you serving over in Iraq right now?" and "Just wait until you have to work overtime to support a family of your own some day."

"I understand that it's a charged political event and there's going to be some head clashing, but I didn't think it would be that bad," Taylor said.
