Kentucky [3], Oregon [4] and Arkansas [5] had their congressional primaries on Tuesday and, as usual, Congresspedia's Wiki the Vote [6] project is on the case with which candidates made the cut for the November ballot.

Well, Arkansas sort of had congressional primaries - as best we can tell, every member of its incumbent congressional delegation faced no challenge from within their own party or from the other major party, so each will face only Green and Libertarian challengers in the fall. Oregon and Kentucky, which both have a Republican senator up for reelection and at least one House member retiring, had vigorous primaries.

Each candidate and incumbent has a profile within Congresspedia's Wiki the Vote [6] project, which you can find at the Oregon [4], Arkansas [5] and Kentucky [3] portals, or through the full listing of the primary victors below. We need your help to find out more about these candidates, so if you know something about them please add it to their profile. (You can always contact [7] one of the staff editors for help.)
