On Saturday, Scott Walker hopped in the clown car. along with the other GOP presidential hopefuls, and descended upon Iowa.

Citizens United President David Bossie introduced Walker with a Gish Gallop that rivaled all of Walker's speech in the number of lies told. While I won't go into all the lies that Bossie told, I feel the need to point out two things.

One, the only time Milwaukee County taxes didn't go up was the one year that Walker took himself out of the process by vetoing the entire budget.

Secondly, Walker never asked the unions for any concessions. He was afraid to come to the bargaining table. Another thing Bossie failed to mention is that Walker's little political stunt cost Milwaukee County taxpayers more than $12 million.

But I digress.

When Walker came strutting out onto the stage, he did so to the song "Shipping Up To Boston," an Woody Guthrie song covered by the Dropkick Murphys. As the gentle reader is already aware, Republicans love to use popular rock songs without permission. Apparently, there are only so many Ted Nugent songs to go around.

Sadly, this is the second time a Wisconsin conservative stole their music. The first time this happened, DKM was direct about their feelings on this theft:

We just got word that Wisconsin State Rep and Speaker of the State Assembly Jeff Fitzgerald used "Shipping Up To Boston" as his walk-on song yesterday at the Wisconsin GOP Convention in Green Bay.

The stupidity and irony of this is laughable. A Wisconsin Republican U.S. Senate candidate - and crony of anti-Union Governor Scott Walker - using a Dropkick Murphys song as an intro is like a white supremacist coming out to gangsta rap!

Fitzgerald: if you and your staff can't even figure out your music you might wanna give up on the politics!!!!!

We stand beside our Union and Labor brothers and sisters and their families in Wisconsin and all over the U.S!

When Walker stole their music, their response, via Twitter, was quicker, more direct and terser:

While Republicans were laughing at Walker's trolling the band, they quickly switched to faux outrage and have been threatening to boycott the band. That in itself is hilarious. I can't imagine one of these stuffed shirts attending a Celtic punk rock band concert or buying their music in the first place. As we already know, when it comes to music, if it's not on Lawrence Welk, the Republicans don't know it.

And if there were any doubt about where DKM stands, here is a video of a song they played in Madison as they stood in solidarity with the protesters:
