Wisconsin Gov. Scott Walker (R), who's trying to generate buzz for a possible 2016 presidential run, had to fire a campaign aide today for her past racist Twitter rants against Latinos—the second such incident to rock Walker's administration since last summer.

The Milwaukee Journal-Sentinel reports that Taylor Palmisano, Walker's deputy campaign finance director, was let go Tuesday after activists pointed out her old grumpy "fuck"-filled tweets about "illegal" people who were bothering her on the bus and in the library by being... well, just by being:

In one, Palmisano, 23, complained about an individual who was doing custodial work in a library in which she was working.

"I will choke that illegal mex cleaning in the library. Stop banging (expletive) chairs around and turn off your Walkman," she posted on March 9, 2011.

Two months earlier, she went to Twitter to write about her bus trip from Pasadena, Calif., to Las Vegas after watching the Wisconsin Badgers play in the Rose Bowl: "This bus is my worst (expletive) nightmare Nobody speaks English & these ppl dont know how 2 control their kids #only3morehours #illegalaliens."

Palmisano has since deleted her Twitter account. This was the second such firing since August, when another Walker aide—Steven Krieser, assistant deputy secretary of the Wisconsin department of transportation—lost his job after writing on Facebook that illegal immigrants were the spawn of Satan:

[W]e get to be treated to the incredible chutzpah of hundreds of thousands of these criminals marching in the streets in broad daylight, demanding all the benefits of citizenship from a country whose laws they are breaking even as they are standing there. The illegals themselves have bred the animus that many American citizens feel toward them You may see Jesus when you look at them. I see Satan.

Krieser added in that post that critics were wrong to say "that opposition to illegal immigration generally is driven primarily by racism."
