CT-5: This is the only possibly competitive district. The incumbent is Elizabeth Esty who was first elected to the seat in 2012. In 2014 she won the seat by a 53%-46.1% spread. This district was won by Obama 53.5%-45.3% in 2012.
Senate: Richard Blumenthal will be running for reelection and is in basically no danger of losing his seat.
President: If you believe a Quinnipiac poll from this spring, Clinton will win this state by a margin somewhere from 18%-25%.
Honestly, nothing to see here.
