We suggested some weeks ago, when House Speaker Jeff Merkley entered the race the the U.S. Senate next year, that over time, odds were that he and earlier entrant Steve Novick likely would have the Democratic field mostly to themselves.
And since then, other prospects indeed have been dropping off, including state Senator Alan Bates of Ashland and now Jeff Golden, who had gone so far as to leave a job behind to consider the run.
Golden was a host on Jefferson Public Radio at Medford, and quit that job to consider the race. He may go back to it (it's not yet been filled) in coming weeks.
Could be that someone else in additional to Merkley and Novick wind up on the Democratic primary ballot. But theirs are likely to be the only candidacies of substance.
