But the PCCC has started the year on the wrong foot, and it needs to chalk up a victory to avoid looking ineffective. The PCCC candidate in Illinois's 10th District, ex-MoveOn activist Ilya Sheyman, lost a high-profile Democratic primary to businessman Brad Schneider by more than eight percentage points in March. And last week, the finance director of another endorsee, Connecticut state House Speaker Chris Donovan, was arrested for laundering campaign contributions from lobbyists, damaging the favorite in Connecticut's 5th District. Now, Griego and Saldana are both locked in difficult battles for their seats' Democratic nominations. Griego has been tied with Michelle Lujan Grisham in every poll that came out in the last weeks of the campaign, and Saldana's main Democratic antagonist, Scott Peters, has spent over $1.4 million on his primary campaign -- five times more than Saldana. The PCCC has faith in its candidates' ground games, and that could prove the difference in one or more races tomorrow. But the group has had a rough start to the year, and the difficult elections coming up Tuesday night mean there's a real chance it could get rougher when results start pouring in.
