MADISON - As the rest of the nation solemnly marked the anniversary of the Sept. 11, 2001, attacks, in which airplanes were taken over and used as weapons of terror, Scott Walker used the day to at least twice proclaim himself the victim of "hijacking."

In a Twitter post and in public statements, the Republican candidate for governor used the term in a spasm of self-pity to describe his flailing campaign.

The insensitive gaffe comes on the heels of Walker using a boxing metaphor to refer to Tom Barrett, who nearly was slain intervening in a domestic dispute the year before; and after his top campaign staff used a racially-insensitive video to mark the Milwaukee visit of President Obama.

"A candidate for high office with any sense of honor, dignity, taste or class might pause before using the term "hijacking" to refer to his political fortunes on a day yet fresh in the memory when so many Americans lost their lives because of the most notorious hijacking in our history," Democratic Party of Wisconsin Chair Mike Tate said Sunday. "Scott Walker is not that candidate."
