MSNBC contributor Sam Seder on Monday night said that "suicide may be the only option" for Republicans due to the polarization caused by President Donald Trump.

Seder, the host of the left-wing "Majority Report" radio show, and Washington Post columnist Jennifer Rubin appeared on MSNBC's "All In," where they discussed Republicans in Congress abandoning Trump in the future if things became more toxic.

"I think the [Rep. Jim] Himes calculation is correct, right? They will abandon him if and when it's political peril," host Chris Hayes said. "The question is at what point that would be the case. Again, they're underwater."

Hayes' quote about Himes was referring to his comments earlier in the show, where he said Republican leaders like Senate Majority Leader Mitch McConnell (R., Ky.) will distance themselves if Robert Mueller's Russia investigation negatively affects Trump's approval ratings.

"When you look at the map, right? You look at where Trump went into those red states and he helped," Seder said. "The problem is that the polarization is such that suicide may be the only option for a lot of these people. Honestly."

Rubin and Hayes laughed at Seder's suicide comment, prompting Hayes to say Americans are watching it happen in "slow motion."

"We're looking at national numbers, but knowing that the president is elected on a national level, they are elected in their very red state or they are elected in their very red district," Seder said, prompting Hayes to reflect back on the midterms and how nearly 40 Republicans were "purged."
