If you have any doubt about the intellectual capacity of the Democratic Party or their ability to stick to talking points which say nothing, you need only look at the Chairperson of the DNC:
"We were just kibbitzing about the weather and things...." Of course when a sitting and relatively senior member of Congress in his late forties is sending pictures of his bulging Jockeys to 21-year-old sycophants in Seattle that is strictly a "personal matter which he is dealing with." It doesn't reflect on the party or the House of Representatives in the slightest.
A standard of behavior is irrespective of party affiliation. Running around acting like a high-school sophomore in a hormonal meltdown is not statesman-like behavior.
