Rebound - Jeff Jacoby writes that President Bush should have responded more forcefully to the charges leveled against him. But he also feels that Bush will bounce back because the Democrats offer nothing as an alternative: “Like the Kerry campaign in 2004, the Democratic Party in 2005 pumps out great foggy clouds of platitudinous bombast, but rarely counters Bush's policies and performance with a well-defined alternative of its own. If you can't beat somebody with nobody, as the old maxim has it, you also can't beat something with nothing. And so far, as Howard Dean demonstrated on ''Meet the Press" the other day, the Democrats' ''vision thing" is a whole lot of nothing.” Yeah, everybody’s still buzzing about that train wreck.
