Democrats, Berkley Violate Election Laws?

From the LVRJ:  Republicans are hitting Democratic U.S. Rep. Shelley Berkley with new allegations of misconduct.
Washoe County Republican Party Chairman David Buell told The Associated Press he filed a federal election law complaint Friday against Berkley and the Nevada Democratic Party for coordinating on her U.S. Senate campaign.
Berkley is running against four little-known Democrats in the June 12 primary, but Nevada Democrats have been helping her campaign for months because she is the presumptive nominee.
Buell said federal campaign law only allows state political parties to coordinate with their official nominee. He points to two campaign mailers promoting Berkley's work with veterans and paid for by the Nevada Democratic Party as a sign that the Democrats are not following federal law.

This isn't the biggest election law being violated, if it is a violation to begin with.  It probably is more of a way to get under Berkley's skin more than anything else.
But if it is a violation of election laws, it shows once again that rules mean little to Democrats when it comes to elections.
