Very. Bush's direct response to 9/11 was actually pretty good, reassuring and energizing. His initial entire into Afghanistan was pretty good, quite timely, and VERY popular. The invasion of Iraq was a mistake, but it wasn't really part of his "9/11 handling."
If Clinton were President, he would likely have said, "Turn over Osama or we'll cruise missile you." The Taliban would ignore him and we'd send some cruise missiles to "bounce rubble." Then Clinton would have to figure out what to do next, probably more cruise missiles. We'd look impotent (arguably one of the things that lead to 9/11) and there might be more attacks.
Carter would almost certainly have handled it FAR worse (think Iran hostages) and Gore and Obama might well handle like Clinton, with nothing but cruise missile and/or drone strikes.
Um, no. None of these guys were peaceniks, and post-9/11, all of them (Clinton, Gore, Obama, even Carter) would have invaded Afghanistan and moved to topple the Taliban. This wasn't a minor incident and the impulse to do something dramatic ran across the entire political spectrum. Not at all akin to the atmosphere after the embassy bombings (which led to the Cruise missile strikes).
