Tammy Duckworth’s victory over the incumbent Republican senator Mark Kirk was one of the few pieces of good news for Democrats on November 8th. A double amputee and veteran of the Iraq war, Duckworth previously served as the Director of the Illinois Department of Veterans as well as the Assistant Secretary for Public and Intergovernmental Affairs in the United States Department of Veterans Affairs.

Former congressman Todd Young, who also served a decorated career in the Marine Corps, will replace the retired Dan Coats in Indiana. He has previously sponsored legislation such as the ‘Fairness for Families Act,’ which delayed the introduction of mandatory individual healthcare coverage, as well as the ‘Save American Workers Act,’ which sought to define a full time worker as someone working 40 hours a week, in order to prevent companies from reducing contract hours in order to avoid the healthcare mandate.

New Hampshire – Maggie Hassan (D)

The former governor of New Hampshire, Maggie Hassan also defeated the incumbent Republican Kelly Ayotte by a narrow 1,067 votes. A staunch supporter of Planned Parenthood, Hassan has said her top priorities in the Senate will be protecting abortion law and tackling climate change.

Replacing former House Majority Leader Sen. Harry Reid, former Nevada Attorney General Catherine Cortez Masto will become the first Latina woman ever to serve in the Senate.

She defeated Republican Joe Beck by 47 percent to 45 percent.
