Who are the most vulnerable Senate Republicans in 2026?

Contributing sentiments towards policy:

61% : Tillis is considered a moderate Republican for his commitment to Ukraine funding, support for gun control legislation that expanded background checks and implemented red flag laws, voting to codify same-sex marriage and supporting legal pathways for Deferred Action for Childhood Arrivals recipients.
39% : He went against his more conservative colleagues by voting to certify former President Joe Biden's victory over Trump in 2020.
37% : Former Vice President Kamala Harris won Maine in 2024, but Trump still secured one electoral vote for winning Congressional District 2. Republican Sen. Susan Collins is considered another moderate Republican - which could serve her once again in the politically split state.
22% : She has not shied away from criticizing Trump either, slamming his Jan. 6 pardons and proposed cuts to the National Institutes of Health grants.
15% : Maine's Democratic Gov. Janet Mills, who sparred with Trump over transgender athletes playing in women's sports, has not ruled out a run for Collins' Senate seat.
14% : While Cornyn is solidly conservative and has supported Trump, he has expressed private disagreement with the president on issues such as budget deficits and border security.
11% : Cassidy voted to convict Trump during his 2021 impeachment trial, alienating him from the Trump-loyalists of the party.
