We have to find a top-tier challenger soon - Sununu is going to rasie a ton of money for this race, mostly from the CFG and their scumbag friends.
In New Hampshire, there is no real bench for either party. We don't have elected offices like AG or Lt Governor, and we just elected Democrats to Congress this past election (neither of whom will run). Marchand could end up being the candidate against Sununu.
Whoever runs against Sununu will have money. The DSCC will pump a lot of money into this race and the Democrat will receive lots of national money from this being a top pickup opportunity.
And you also need to remember that this is a small state and you don't need $15 million to win a Senate race......$5-8 million will work just fine.
