INTERESTING GUEST LIST…. When I first received an email yesterday telling me that Michelle Malkin would be a guest on ABC’s “This Week with George Stephanopoulos,” I thought it was a joke. I assumed it was an example of exaggerating for comedic effect — as in, “The Sunday morning shows’ guest lists tilt to the right so often, one of these days, we’ll even see Malkin on.”

It turns out, this wasn’t a joke.

Here are the scheduled guests for the Sunday public affairs shows and other weekend programs….

This Week hosts Treas. Sec. Tim Geithner and ex-Fed Chair Alan Greenspan. The roundtable is author/columnist Michelle Malkin, Atlanta Journal-Constitution’s Cynthia Tucker, Bloomberg’s Al Hunt and Wall Street Journal’s Jerry Seib.

This is the Malkin of “The Defeatocrats’ Cheer.” The Malkin of “In Defense of Internment.” The Malkin who went after a 12 year old and his family over their support for expanding S-CHIP. This Michelle Malkin.

Malkin has her shtick, and she’s a very effective advocate of far-right ideas. But her appearance tomorrow is a reminder that it doesn’t matter how right wing a political observer is; if he/she has something provocative to say, he/she will get airtime from major media outlets.
