I'll say this.. the truth is what is important. If the GOP can establish legitimate proof Biden did anything illegal, let's go to court... Get every Alphabet agency involved, leave no stone unturned. If Biden did anything illegal fry him. If the DOJ or FBI find credible charges, go for it. You will NOT hear me say it's a witch hunt if either of those are involved. Heck, even an special prosecutor I will go with, even a Trump appointed official. Let's get to the truth.
With regards to some House Republicans proposed Biden impeachment, there is a certain irony, and this is that the Democrat controlled Senate won't uphold it. Does this seem familiar. Since turnabout is fair play, at least Biden's detractors could go around reminding people that Biden was in fact impeached just as some anti-Trump folks did when he was impeached.
In Trump's second impeachment, 10 GOP members joined the Democrats with votes to impeach Trump. In the first impeachment the vote was strictly along party lines.
How many of the 222 House Republicans would vote to impeach Biden? Do you think it would be all of them or do you think some Republican Reps would vote against impeachment, risking the wrath of the public. It seems highly unlikely that any house Democrats would vote for his impeachment not that they would need to.
Imagining the possibilities of a Biden impeachment being confirmed by the Senate is even more nail biting since the split is 50/50 with VP Harris breaking a tie.
