“They will have the numbers”
To clarify: assuming a midterm victory, the GOP will have the numbers in the House to pass an impeachment resolution, but nothing more. Any impeachment will be dead in the water in the Senate due to the 2/3 supermajority requirement.
Short of Biden losing an election and whipping up an insurrection on the Capitol, Senate Dems are not going to impeach Biden for anything — because that is the abysmally low bar for Presidential misconduct that Republicans have set for themselves. And they didn’t even clear that one.
Republicans will impeach Biden anyway because it will deliver many opportunities for partisan grandstanding, soundbites and zingers that will play well on Fox News in the evening, even if it ends up repelling most average voters who would rather have solutions to problems.
That’s my prediction, anyway. We’ll see!
