Considering that Sarah Palin has cited Margaret Thatcher as a hero, this has to sting:

Margaret Thatcher, the former British prime minister, is well respected by Sarah Palin, but it doesn't appear that the feeling is mutual.

Recently the former Alaska governor revealed plans to take her "One Nation" road show across the pond next month, with a stop in London as she makes her way to Sudan....But the woman affectionately dubbed the Iron Lady isn't interested in meeting with Sarah Barracuda during the hockey mom's trip.

"Lady Thatcher will not be seeing Sarah Palin. That would be belittling for Margaret. Sarah Palin is nuts," an unnamed "ally" told the Guardian.

Of course, other sources claim that Palin had no idea who Thatcher was before the 2008 campaign, so maybe it doesn't sting, after all.
