Top 10 Worst U.S. Senate Candidates of All Time

Roy Moore

Even without the scandals, he was pretty bad. He believed in theocracy and argued that all constitutional amendments before the 13th should be abolished, which would have meant a return to slavery. He was also involved in numerous conspiracy theories. He is literally the reason there was a Democratic Senator in Alabama from 2018 to 2021.

Easiest choice by far. This guy was a child predator. Whether it was consensual or not, that behavior was sick and disturbing. With any other candidate, the Republicans would have won. That's how awful this guy is.

Kelly Loeffler

Appointed by Brian Kemp after Johnny Isakson retired due to health issues, this woman was robotic. On top of that, her insider trading scandals only made it worse.

Raphael Warnock

He probably would have lost if his opponent hadn't been terrible. This guy had some nasty scandals, including running over his now-ex-wife's foot and covering up for a man who poured urine on kids at a camp. His campaign was well-run and focused on Loeffler's scandals, which prevented his own from coming to light. In 2022, they will probably bite him hard. "Radical Liberal" Raphael Warnock better watch out in 2022.

Kyrsten Sinema

I am talking about Sinema in 2018. She has vastly changed and would likely win re-election due to having swing voter appeal. However, in 2018, she could have lost due to her previous ties with a socialist party associated with the Green Party, as well as her statement that she doesn't care if citizens join the Taliban, and her calling Arizona the meth lab of the country. Nowadays, I think Sinema would win re-election because she has proved to be an all-around moderate who appeals to swing voters.

A great candidate in the general election, but she will probably be primaried by a more progressive candidate like Ruben Gallego.

Martha McSally

McSally has an appealing background as the first female fighter pilot, but she is not a good speaker and is a proven flip-flopper on issues. There is a good reason she lost both times.

Jim Renacci

Jim Renacci didn't have skeletons in his closet like some others. He ran against Sherrod Brown of Ohio in 2018. He was practically a last-minute fill-in candidate after Mandel suddenly dropped out. Brown was the only Democrat to win statewide office in Ohio in 2018.

Roy Blunt

Roy Blunt has been elected senator for several terms in Missouri. He is an establishment neocon that few people in the state like. In 2016, Trump won the state comfortably, while Blunt won by less than three percent. That is simply because the people hate the guy.

Ed Markey

This Democrat senator was generally unpopular with most people. The Democrat establishment tried to run Representative Joe Kennedy III to primary Markey. Kennedy had high-profile endorsements, including one from Nancy Pelosi. Democrats usually avoid trying to primary their incumbents, but this guy was not on good terms with most people. However, he did win his primary in 2020 and won re-election.

Lisa Murkowski

One of the most hated senators, she is a Rockefeller Republican (liberal Republican) in a deep red state. Democrats will never have a Joe Manchin type in a deep blue state. Murkowski will likely get primaried in 2022.

Mitch McConnell

This miserable, turtle-faced old sack of bones has been holding Kentucky and America back for nearly 40 years, and he continues to slow America down.

Maggie Hassan

Maggie Hassan, the former Democratic governor of New Hampshire and a current senator from that state, has extremely low approval ratings for both positions. New Hampshire dislikes incumbents, and if Chris Sununu runs, Hassan will almost certainly lose.

Lindsey Graham
