NOPE - the "anti-incumbent" call was manufactured by the mainstream media as a means of deflecting from the anti Obama-Pelosi-Reid sentiment.
This election is not anti-incumbent and never has been - it's ANTI-DEMOCRAT-ANTI-OBAMA-ANTI-CONGRESS. Period.
Republicans who were up for re-election who were seen as aiding the Democrat agenda were put in danger. These candidates either were able to convince voters they were conservative, or face being booted out.
Democrats are now running ads against Obama-Pelosi-Reid. Democrats are joking about Pelosi dying. Obamas poll numbers are stagnant, the Congress approval numbers are at historic lows, and the GDP now enjoy historic margins on the Generic Ballot.
The Dems are panicking and for good reason - they are about to get destroyed in November. That acceptance is already being undertaken by the Democrat Machine, and now they are scrambling to make possible Obama's re-election, which at the moment, appears far more difficult than just a handful of months ago...
