This morning, Punchbowl has an item about Republican senators pledging not to tamper with the filibuster if they win control of Congress and Trump wins the presidency in November. (Yes, unfortunately we have to discuss these things.) Democrats don’t believe them. But Republicans insist they’ll say no to Donald Trump if he demands it. And they can point to 2017 and 2018 when he made those same demands and they refused.

Let me start by noting that Democrats absolutely shouldn’t believe them. Trump is Trump, after all, and Republican senators are Republican senators. But with that said, it is worth reminding ourselves that quite apart from believing Republican pledges or thinking Republicans are invested in values other than power, Republicans actually have interests in the filibuster that Democrats do not.

TPM’s Josh Kovensky will be liveblogging closing arguments in the Trump trial beginning at 9:30 a.m. ET Tuesday. Join him and us for a big week, with the jury finally getting the case.
