Astro-vandalism, newest weapon of the left?

It appears that a man who is an accountant for a number of Democratic-leaning political committees was caught vandalizing the Colorado Democratic Party headquarters. Of course the State Democratic Party Chairwoman was quick to blame local tea party people. Why let the truth get in the way of a good narrative, right?

Will the fact that this was done by an unpaid "volunteer" upset the SEIU? Is this not normally a union job?

Update: that last comment was meant as a joke but it appears that this person might have actually been paid (by the SEIU?) to vandalize the office.
