Yet while the Beltway establishment frets about the alleged damage this drawn-out contest is doing to the Democratic Party, in reality, it's been an almost unalloyed good.
For one, the frenzied organizing around the country has proved a catalyst for dramatic party building in states that had been Democratically dormant. State after state has reported record turnout, and thousands of new Democrats are registering in advance of each contest. In upcoming Pennsylvania, Democrats have gained a net 200,000 registered voters over Republicans this year; that number is 105,000 in North Carolina.
The party can now take advantage of the infrastructure both campaigns leave behind. The unprecedented level of participation and organization not only reinforces Blue states, it improves Democratic odds in traditional swing states. In fact, the tide threatens to make GOP stalwarts like Texas up for grabs this fall.
