Late last week, Mr. Hardy announced his candidacy. Yesterday, Mr. Horsford declared that he, too, will be a congressional candidate in 2018. The former Congressman still faces serious Democratic primary opposition in the person of state Sen. Pat Spearman, who says she will not yield to Horsford. Assuming he wins the party nod, the general election will feature a re-match of the 2014 campaign, but now between former Reps. Hardy and Horsford. This pairing would guarantee that one of the two returns to Washington.
