Gergen to the Rescue?

David Gergen has been omnipresent on the tube as of late -- from CBS' Early Show to MSNBC's Hardball to CNN's Situation Room and Lou Dobbs -- telling the world how Bush's presidency "has almost collapsed" and how Reagan turned Iran-Contra around when "he brought in Howard Baker and Ken Duberstein and Colin Powell."

Do you get the sense that he's auditioning to be Karl Rove's replacement? The wise man who saves the day?

For those keeping score, that would mean serving under five presidents for David Gergen.
