The Democrats now have a larger voter registration edge over Republicans in populous Clark County than in 2008, when the party swept to top-to-bottom victories.

The numbers continue to make Mitt Romney's path to victory very difficult and Dean Heller's road to a full Senate term quite problematic. Barack Obama won Clark by 19 percentage points in 2008 en route to a smashing 12-point statewide win. I doubt he'll do that this cycle, but if he wins by 12 to 14, he will win the state pretty easily.

The latest Clark County numbers show the Democrats now have a 125,441-voter lead. It was 125,218 in '08. Considering how different the world is -- not so hopey and changey -- that is remarkable.

The statewide edge, as of yesterday, is a little more than 86,000. And they are still counting thousands of new registrations in Clark
