There is no democrat running for the Kansas seat.
Greg Orman has run before as a DEMOCRAT.
Greg Orman has given tens of thousands of dollars to Obama.
Greg Orman has given tens of thousands of dollars to the Democrat Party.
On that point you are quite wrong on several counts. Chad Taylor won the Democrat primary and is the Democrat candidate. The Kansas Supreme Court is probably going to remove him from the ballot at his request, but they haven't done it yet.
Greg Orman is running as the Independent candidate, but he is no such thing. He is a Democrat, has the blessing of the Democrat Party leadership, and is committing a fraud on the people of Kansas.
Go to Ornman's site. If there is not a Democrat running for the seat could you tell me what a fricking Democrat is?
The Democrat is Greg Orman our Bernie Sanders.
