At least at some level. Take this for instance:
The staff of U.S. Rep Marty Meehan wiped out references to his broken term-limits pledge as well as information about his huge campaign war chest in an independent biography of the Lowell Democrat on a Web site that bills itself as the “world’s largest encyclopedia,” The Sun has learned.
The Meehan alterations on Wikipedia.com represent just two of more than 1,000 changes made by congressional staffers at the U.S. House of Representatives in the past six month.
Unbelievable. Why are these guys afraid of having their actual record available easily to the public? Because they are all corrupt.
