The 2018 Senate elections were held on November 6, 2018 to elect class 1 Senators to the Senate. Those elected would serve a six-year term from January 3, 2019-January 3, 2025.

After the 2010 Democrats thought they would lose their majority in 2012 since they had 23 seats to defend while the Republicans only had 10. They won many races in this class' previous elections in 2000 and 2006. Along with President Obama's re-election the Democrats pulled off stunning victories across the country defending all of their incumbents, only losing one open seat and gaining three additional seats.

However the math stands against them again. They will have 24 Democrats and 1 Independent who caucuses with them to defend against just 8 seats for the Republicans. They will also be defending seats in red states like Indiana, Missouri, Montana, North Dakota and West Virginia in addition to seats in perennial purple states like Florida, Ohio, Pennsylvania, and Virginia.

4 Democratic women and 3 Republican women or more could be elected to the Senate increasing the number to 31 women with 23 Democrats and 8 Republicans.

Only 2 Democrats lost their seats, Indiana's Joe Donnelly and Missouri's Claire McCaskill both of whom won in 2012 because their opponents' campaigns imploded. North Dakota has a tendency to vote for a personality regardless of party affiliation, thus Heidi Heitkamp's re-election.
