There's no question that Republicans are benefiting from having redistricting occur after the November election and not before it. But there is a difference between being better off and being in good shape.
Republicans are poised to ride a wave election, conceivably as large as in 1994, and Exhibit A of their success may well be pronounced "Speaker John Boehner." But if you step back, it's also likely to be a temporary bump on a road toward Democratic dominance.
With the exception of one poorly-chosen word, it seems to me to fit the classic definition of a "Washington gaffe" -- accidentally speaking a bald truth, and having to immediately apologize for such unseemliness.
Other interesting news from Republicanland is a new poll showing that, given three choices, voters state who they'd likely vote for in the 2010 election in the following order: (1) Democrats, (2) Tea Partiers, (3) Republicans.
