"You didn't get on Ed's case for posting articles directly from a republican source and the actual article doesn't seem to do exactly what you criticize here."
A representive or official of the Republican or a representive of Democrat party is would be a better source than "Eric Russell, former Voters Outreach employee."

Though I did find a Eric Russell with a google search:
http://www.bangornews.com/editorialnews/article.cfm?ID=435202
He's a news staff writer- though I'm sure they are lots of Eric Russells around maybe at best around 50% chance it's same guy [from Maine- but it's possible he travelled right across country]
Or this:

That's in Utah.
Anyways, there is lots of them.

"We don't know who shot at the GOP offices in various cities it is just republicans believe democrats are doing it. It is just as likely disgruntled ex-employees or ex-spouses or other personal enemies."

Well, I think we had some union members saying they doing some of this. But shooting bullets and such- who knows. May not have even happenned- dirty tricks are too common and the well known demonstrated violence from the Lefties might "invite" the idea starting a false rumor. As Mary Anne said it's most trustable if someone is actually arrested for a crime or at least a police report filed [it's a crime to file a false police report].
