People respond in strange ways to the prospect of losing your job and knowing that there is not a thing that you can do about it. Throw in the public disgrace, add a chance of incarceration and most people will pass some sort of breaking point. See, for example, the increasingly weird behavior of Republican candidates.
* Mark Foley (R-FL) may be gone, but Tom Reynolds (R-NY) and Dennis Hastert (R-IL) remain as living symbols of how not to manage a crisis.
* Don Sherwood (R-PA) strangles his illicit mistress, she survives, and now he wants voters to forgive him. Polls suggest that he should have tried not strangling his mistress.
* Katherine Harris (R-FL), the eternal sunshine of the clueless mind.
* The president‘s practically incoherent press conference. While not a candidate, this election is more or less a referendum on him. And it seems fairly likely that losing both Houses will eventually lead to jail.
* The strain of maintaining the “moderate” facade seems to have pushed Chris Shays (R-CT) over the edge.
* Knowing that he will lose his race might be what caused Rick Santorum (R-PA) to flip his lid on live TV.
* Bob Ney (R-OH) pleads guilty to corruption (possibly the least surprising development so far this year) but declines to resign until after the election. That kind of self-interested hubris would be fine if this was the 2002 midterms and the terra-sploitation steamroller could. not. be. stopped. But it ain’t 2002. No doubt the Dems will appreciate having a living symbol of GOP corruption hanging around Congress. [Correction] Ney will step down next week. Smart boy.
* [Update] John already has this above, but crazy Curt Weldon [R-PA] of Able Danger fame will face an FBI investigation over charges of corruption and nepotism.
Just a random sampling from the recent news.
