1. Yes, it’s galling that Senate Democrats can dish it out but can’t take it. Harry Reid, for example, voted against cloture at least 25 times on 13 different nominees of George W. Bush, yet he’s outraged that Republicans defeated a grand total of seven cloture motions on Obama nominees. As for D.C. Circuit nominees specifically:
b. Bush nominated another outstanding candidate, Peter B. Keisler, to the D.C. Circuit on June 29, 2006. After Senate Democrats took control of the Senate, they never moved Keisler’s nomination out of committee. Keisler’s nomination died some 2-1/2 years after it was made.
c. Bush did succeed in getting four of his nominees confirmed (a net of three, as John Roberts was elevated to Chief Justice), but only after extended delays and massive obstruction. Roberts’s nomination took 729 days to confirmation. Janice Rogers Brown’s took 684 days and encountered two cloture defeats. Thomas Griffith’s took 400 days. And Brett Kavanaugh’s took 1,036 days, including an unsuccessful filibuster effort.
As I elaborated in point 2 here, the hypocrisy charge applies with far more force against Senate Democrats (and voices on the Left like the New York Times) than against Senate Republicans, as Democratic resort to the filibuster against Bush nominees dramatically altered the terrain.
