This post is misleading. Trump could be impeached by the House with a simple majority of 218 votes, but the Senate would likely acquit, as a supermajority of 67 votes is required. This account has made this post multiple times, likely for engagement.
I think it is a fair prediction that a lot of things will change in the next two years. The Senate might actually change less than the rest, with only a third of the Senate up for election. Maybe a little more than a third, because there might be Senators leaving office early, but not much more.
A quorum of 51 Senators is needed, and two thirds of those must vote for conviction. That means you need 34 votes for conviction, and 49 Senators not showing up. That is more Senators being willing to let trump be convicted(83), but fewer having to be committed to convicting him. On the other extreme, you need 67 voting to convict, and no one just choosing not to vote.
So let's find where in the middle that all meets to make it possible. If there is a huge obvious criminality on the part of trump, combined with huge failure. It would not be unreasonable for there to be 36 seats up for election in 2026, with 13 being Democrats, and 23 being Republicans. If Democrats win two thirds of the elections, then the split would be 58 Democrats to 42 Republicans. If all 58 Democrats vote for conviction(very likely), and 13 Republicans are so disgusted by trump, they chose not to vote(less likely, but possible)... That is conviction.
Greater shifts have happened before. I am not saying this will happen, but it is certainly possible... though admittedly farfetched.
It is a good idea to setup the groundwork now. If nothing else, it reminds voters of trump's corruption.
