Yup. It reminded conservatives of just how extreme a leftist Rudy is.
I think the Rudy campaign is showing a lot of parallels with the Howard Dean campaign from around late 2003: early lead, good fundraising, base of support from the far left of his party. The flameout is impending.
I also see parallels with the ‘04 Kerry campaign, in that the focus is Anybody But Hillary, many support Rudy mostly because they think he’s electable, and many believe that Rudy’s 9/11 experience (like Kerry’s vietnam experience) will check-mate the democrat candidate (meanwhile there are plenty of 9/11 families who have said they are going to swiftboat Rudy if he wins the nomination).
