Tea Party rally at the Wisconsin State Capitol, this Saturday.

It's the tax day day after tax day rally.

We went to last year's tax day Tea Party rally, and it was a pretty good photo op: here, here, here, and here. It seemed like a big crowd, with 12,000 people, but that won't seem big after all the protests we've had here over the last 2 months. But the Farmers' Market starts this Saturday, so there will be lots of people on the square. You won't be able to tell who came for what.

Major Saturday protests — which took place five consecutive weekends after [Gov. Scott] Walker unveiled his proposal Feb. 11 — drew as many as 100,000 people to the Capitol. Demonstrations, even in smaller numbers, could disrupt the 39-year market tradition that can draw as many as 20,000 shoppers to the Square when the weather’s nice.

Yeah, there will have to be anti-Walkerites there too. They'll have to take advantage of another Saturday and the new audience that is the Farmers' Market shoppers. Plus, they've got to show that they outnumer the tea partiers.

It should be interesting.
