Democrats have filed their first legal challenges before polls even closed on Election Day, asking for an extension of voting hours in Connecticut and questioning the denial of provisional ballots in Illinois.Sen. Robert Menendez (D-N.J.), the chairman of the Democratic Senatorial Campaign Committee (DSCCC), told reporters at party headquarters that officials had gone to court in two states. In Connecticut, the party has asked for a one-hour extension of voting in Bridgeport, a Democratic stronghold where turnout was reported so high that officials ran out of ballots, Menendez said.
