With the GOP’s sweeping victory in the mid-term elections, observers were already questioning the fate of Treasury Secretary Tim Geithner in the new Congress. In exit polling, most voters ranked dissatisfaction with the economy as a key factor guiding their decision. Since Geithner is one of the few members of the White House economic team still in place, analysts said House Republicans are likely to target him when they take control next year and press for his removal. Some suggested Obama could jettison Geithner as a sign he is willing to change his approach.
