Actually, this is exactly how Watergate started. In 1972, after the bungled burglary, the DNC Chairman O'Brian instantly claimed it was not a burglary, it was an illegal snoop by the RNC to extract confidential campaign information. The DNC subsequently sued the RNC, naming individuals involved, for a million dollars. As each tip of the Watergate iceberg broke off, exposing another tip, the DNC amended their civil lawsuit, which made the amendment public and the press reported on it. That gave the DNC lawyers the opportunity to subpoena documents and more importantly, to depose all the key players, which were "All The President's Men".
We know the ending. What the entire country snickered at and called a yawn when the suit was filed, turned into the downfall of a president and years in prison for all those involved. On the day Nixon resigned, the RNC quietly settled the suit for 3/4 million bucks.
So this DNC lawsuit does not SET precedent; it FOLLOWS precedent, lol! And lots of names are included, ripe for depositions and subpoenas!
Take a look at today's Rachel Maddow show on MSNBC. The first 20 minutes of it, supported by her solid gold research team, knocked my socks off, because I did not know or remember anything about the "little lawsuit that could...and did..." take down a president. :lol:
