Before we are too quick to call on the law to support our side, consider what happens when that same law is used against us by our opponents. Right now you may want DNC leaders in jail, but I think it would set a terrible precedent for private political activities to result in imprisonment, regardless of our distaste for them. Again, the situation is very different when peoples' Constitutional voting rights are denied (eg, voting in a real election). Then by all means, legal action should be taken.
1) Exclusive use of hand-counted paper ballots in all future US elections.
2) Automatic voter registration, with same-day party affiliation switching as a mandatory condition for all elections that are publicly funded.
3) Restoration of voting rights legislation which would ensure adequate access to polling sites.
So it's cool: no jail time for anybody, just better preventative measures.
