In this year’s Democratic primary races for the Senate, the supreme form of incumbent potency prevails. Four of the city’s six senators—Catherine Pugh (D-40th District), Lisa Gladden (D-41st District), Verna Jones (D-44th District), and Nathaniel McFadden (D-45th District) —face no primary competition. They are virtually assured re-election since, in this overwhelmingly Big-D town, the Democratic primaries in September pick the winners in November’s general elections. Without challengers, they are free to spend their campaign cash (a combined quarter-million dollars as of January, when the latest available campaign-finance reports were due) on whomever they favor in other races. The remaining two—Joan Carter Conway (43rd District) and George Della (46th District)—each face a single, spirited opponent.
