From Al Kamen:

The on-again, off-again rumor that White House Chief of Staff Andrew Card is moving to be secretary of the treasury to replace John Snow appears to be on again.

The question the last time the rumor bounced around was who would replace Card, with the oddsmakers suggesting either Office of Management and Budget chief Josh Bolten or Deputy Chief of Staff Karl Rove. Problem then was said to be a need to await resolution of the investigation into Rove’s role in the Valerie Plame leak to the press. That investigation is supposed to be concluded next month.
