I'm inclined to believe that the Democrats are far more likely to win this race than not, but I'm still perplexed as to why the Democrats only ended up with D-list candidates here. Miller really ought to have run, IMO.
I actually think Sisolak and Giunchigliani are fine. Nevada's population distribution is ridiculously uneven, with nearly 70% living in Clark County. Sisolak is the Chair of the Clark County Commission while Giunchigliani is the Vice Chair. Because of Clark County's population size and economic prowess, the Clark County Commission has been called the most powerful government body in the state (
https://en.wikipedia.org/wiki/Clark_County_Commission). Sisolak and Giunchigliani are well-known in a heavily populated area and have experience managing a powerful political body. The only downside is that they're going to have to do overtime in the northwest, where the remaining bulk of the state's population lives, to make up for their lack of recognition outside of Clark County.
