Yes. They served their role just fine in the 90's when the Democrats had to move to the center to win.
Did they? Judging by the 1994 results, Bill's lack of legislative accomplishment, and the fact that they made
George W. Bush seem like a fresh alternative, I wouldn't say they were the best choice for Democrats in the 1990s. In fact, their sleaze was disastrous for Democrats during that whole period and made rebuilding impossible until they were put on the shelf for a while. For example, in 1996 all the polls were showing Democrats were easily going to retake the House - then the Chinese fundraising scandal came out.
