Two of Alaska's most recognizable politicians -- Gov. Sarah Palin and U.S. Rep. Don Young -- are newcomers to Twitter, but in Young's case, it's not a happy introduction to the social networking site. An impostor had been posing as the veteran Republican congressman this week, while the real Palin is doing the tweeting on her page.

The messages on the Young impostor's site ranged from silly to preposterous and the congressman's aides said they were working with Twitter to take down the page. The site was removed Thursday afternoon.

"Can anything top a peanut butter and marshmallow fluff sandwich?" one posting asked. Another stated, "Just received a memo from the White House: either I sign a loyalty oath to Obama, or 'my life will be difficult.' Insane. (I won't!)"

Palin's Twitter feed was launched Wednesday and had more than 10,000 followers a day later. Those Palin is following include Republican Govs. Arnold Schwarzenegger of California and Rick Perry of Texas, as well as Republican U.S. Sens. Lisa Murkowski of Alaska and John McCain of Arizona -- who made Palin a household word when he named her as his running mate last year in his presidential bid.
