Wow. So a long string of words to reveal yourself as little more than making an attempt at a papartisan gotcha"...asking you to be a bit more detailed in your imaginary scenario shouldnt have caused this much of a conversational meltdown on your part. It was a simple question of what kind of Republican Presidency you envisioned, and you behaved as if you have a wedgie right this second.
Also here is a newsflash, McConnell is the current Senate Minority Leader. He is literally in charge of the ENTIRE Republican Party that is sitting in the Senate. And this would be obvious to you if you had the slightest clue what you were talking about, because he's more than infuriated the Sedition Caucus in the House by not backing their plays. He is THE reason there is something of a rift between Senate Republicans who play more savvy politics, and far right lunatic hardliners in the House...and he's still the type of @sshole who shoehorned in the least qualified SCOTUS Justice in US History via breaking the rule he invented about not approving Justices during election years.
Next time you get asked a question about how Government functions in the US try thinking about it before responding like a 15 year-old who just learned hes getting a D in Civics.
