Senate Race: With Election Day Tuesday, polls show Democrat Chris Pappas narrowly ahead of Republican John Sununu in New Hampshire’s closely watched U.S. Senate contest. The state Attorney General’s office ordered a Washington mail firm and Massachusetts printer to stop sending anonymous ads targeting Sununu and praising candidate Edmund Laplante; all three campaigns and both parties said they knew nothing about the mailers. Governor’s Race: Democrat Cinde Warmington campaigned with Sen. Cory Booker in Concord, urging supporters to turn out, while Republican Gov. Kelly Ayotte and Warmington make their final pitches. Election Readiness: Secretary of State David Scanlan says New Hampshire is prepared for record turnout and that ballot-counting machines are tested and secure. The Justice Department plans to send election monitors to some New Hampshire cities. Ballot Question: Voters will also decide whether to cap local school property taxes, a proposal supporters say could restrain costs and opponents warn could squeeze school programs. Immigration: ICE detained Jessie Laurel Tepler-Mujambere in Colebrook as he drove to Canada, where his family says he had just received citizenship paperwork. DHS says he overstayed his U.S. permission; his family says his work permit was not renewed.
