Democrats, more understandably, seem eager to get back to their standard issues of education, Social Security, health care and the environment, rather than make the election about Clinton. Neither party has scheduled a national advertising campaign touting the Lewinsky scandal or impeachment as the reason to support its candidates, and only a few desperate candidates seem to be planning to use either theme in their own campaigns. The Lewinsky case has drowned out everything else for months, and it's done some damage to Democrats. But the conventional wisdom that it will dominate the campaigns may be conventional, but it isn't wise. In fact, it's going to dissipate as an issue as people get back home.
People are sick of it.
It's certainly in the background, but there is no evidence that it cuts one way or another. GOP prospects in the Senate are much better. What's changed the atmosphere is that Democrats rallied back from despair and formed new battle lines around the argument that House GOP treatment of Clinton was unfair. They teed this issue up before the election to put as many Democrats as possible in an uncomfortable position. They thought they could divide the party, but they didn't.
