That’s satire, right? Grassley and McConnell are well-known RINOs.
RINOs they certainly are, but that doesn’t mean that they are stupid. They are interested in keeping power and they have decided that this move will best support their goal of retaining the majority in the Senate. This is not about political philosophy, it’s about political power. Those Senators who are in a Blue State can hold meetings and tell their constituents that they are doing their best to move the confirmation forward and they are joined by some (like my Senator Moran) who are just too stupid to understand what is going on.
Politics is about deception. The politicians deceive the voters and the voters fall for it.
