Congress: Connecticut is not expected to play a major role in the battle for control of Congress, with incumbent Democrats, including Joe Courtney, running in four of the five districts. Nationally, President Trump and former President Obama have been canvassing the country in the high-stakes fight for a majority in Congress, particularly the House. Democratic Sen. Chris Murphy is a heavy favorite.

Governor: Democrat Ned Lamont and Republican Bob Stefanowski are vying to replace Gov. Dannel P. Malloy. Polls have generally been within the margin of error. Oz Griebel, running as an independent, has been polling in the single digits. Mark Stewart Greenstein and Libertarian Rod Hanscomb also are on the ballot.

Other statewide races: Underticket races for attorney general, secretary of the state, treasurer and comptroller also are on the ballot.

Ballot questions: Voters will be asked whether to approve creation of a so-called constitutional lockbox to keep money designated for transportation projects from being spent elsewhere and whether to place limits on the General Assembly when it attempts to transfer or sell state-owned property to a non-state entity.

Local questions: In Groton, voters will decide on charter changes that include eliminating the Representative Town Meeting and implementing a Board of Finance and an annual budget referendum. Charter changes are also on the ballot in Ledyard, and Montville voters will be asked to spend $10 million over 10 years on road improvements.

Connecticut General Assembly: Both parties hope to break an 18-18 tie in their favor in the Senate. Key races include Republican Sen. Heather Somers and Democrat Bob Statchen in the 18th District and the open 33rd District seat, where Democrat Norm Needleman and Republican Melissa Ziobron are squaring off.
