These are Obama supporters, no doubt. Or many McCain supporters. Hard to tell anymore (via Oregonian blog):

Background:

Oregon’s new drivers’ license rules took effect Monday, and the Oregon Legislature is considering placing the new rules in state law. That sparked demonstrations by groups supporting and opposing the new rules.

The new rules make it more difficult for illegal immigrants to get an Oregon driver’s license, requiring a valid Social Security number and other documentation.

Opponents of the new rules marched around the Capitol in protest, saying the rules are unfair and would end up hurting families. Supporters of the new rules gathered on the front steps of the Capitol, collecting signatures for an initiative that would also limit driver’s licenses to citizens and legal residents. Oregon State Police stood between the two groups.
