MIDDLETOWN, Del. ― This is what democracy looks like. It’s been a chant that has animated marches and protests around the country since the day after Donald Trump was inaugurated president, but it’s been more aspirational than descriptive. On Saturday, in a state Senate district in Delaware that stretches from Middletown to Newark, the voices in the streets turned into votes in the ballot box. In the most expensive special election in Delaware history ― a contest to decide which party controls the state Senate ― Democrat Stephanie Hansen’s 58-42 percent victory over Marino on Saturday ensured that Democrats will maintain control of the state Senate.
