Kennedy's routine support of President George W. Bush in House votes was a central issue for Democrats in the campaign. In June 2006, allegations were made that many references to and photos of Bush had been removed from Kennedy's official U.S. House website; in rebuttal, Republicans said that there were 72 references to Bush on the website and that the changes noted by critics had been made some time ago, as part of the normal updating process. Ben Powers was the only ballot-qualified candidate not to be invited to appear on Minnesota Public Television's "Almanac" program, despite Mr. Powers's offer to fill the space left unfilled by Ms. Klobuchar's decision not to appear with Mr. Kennedy and Mr. Fitzgerald on the program. Green candidate Michael Cavlan appeared on the program twice during the 2006 campaign as a special guest.
