I've been getting a lot of email from Democratic fundraisers lately. They seem very worried about November's elections.First came the highly publicized "Impeachment Red Alert" campaign, in which the Democratic congressional committee warned Republicans will impeach President Obama if they win control of the House and Senate. Though much ridiculed, the "Impeachment Red Alert" effort was a big winner, pulling in $2.1 million in a single weekend.Despite that success, House Minority Leader Nancy Pelosi's mood seemed to blacken in subsequent days as she asked for more and more money.
