Kate O'Beirne and Ramesh Ponnuru have what seems like sound advice for the GOP frontrunner:

What McCain should do instead is to take the fight to the Democrats, explaining why he's against Harry Reid's defeatism, Hillary Clinton's health-care plan, Nancy Pelosi's obstructionism on intelligence gathering, Barack Obama's tax increases, and even Dennis Kucinich's Department of Peace. Conservatives know that McCain can be a tough political combatant. They want to see him turn those skills on the Democrats. They're tired of being on the defensive. Even McCain's opponents in the CPAC crowd will have to applaud as he lays into the Democrats.

Recall that, for conservatives, Giuliani's best moments on the trail were when he went after organizations like MoveOn and politicians like Hillary Clinton. McCain is nowhere near as out of step with his party as Giuliani is. But he could still benefit from some old-fashioned contrast politics.
