Coons has a challenger, but unfortunately it isn’t a progressive primary challenge. It is Mark Turley of Millsboro.
I can’t find any online footprint related to a going campaign, not even on the coo-coo-bananas IPod of Delaware website, but his filing email indicates that he is Mark Turley, Owner/President, of Projected Energy which is a renewable energy consulting firm.
But that is not to say that Turley has any skin n the game. Filing fees are set by the parties and the Ipod filing fees for this office appear to be $0.00.
And BTW, I insist that you check out the Ipod’s coo-coo-bananas web site. I’d post scree shot, but you just don’t get a feel for how out there it is unless you visit it.
