Lets clear the air on this, McConnell nuked the rule for SC judge nominations last year, Reid started it with the lower courts 5 years ago but the Dems left the SC nomination rules alone. I bring this up because people here are still getting this essential fact wrong.
Kennedy, whose seat would be replaced by Kavanaugh is a moderate conservative swing vote, Kavanaugh is notably further right than he is. This nomination will further polarize the SC with another ideologue, Gorsch was also a hard right candidate, but because he would be replacing another hard right judge (Scalia) the balance of the SCOTUS was maintained.
This nomination will tip the scales of the SC with a lifelong judge in his early 50s who holds hard right views and will further polarize the SC for at least a generation. Kavanaugh is too partisan (to fill the seat being vacated) I would much rather see a moderate voice like Garland's filling that seat. Kavanaugh is too far right to not vote along party lines. And regardless of your political viewpoints you should be cautious of a
nominee to the SC who possibly has committed perjury in regards to stolen opposition party documents. On this basis alone I think more vetting is needed to figure out all the facts about what happened there and what his involvement with it was.
Purely speculation, Biden maybe didn't like Garland as a nominee because he was a moderate conservative and not liberal enough. This I think was intentional because Obama recognized the balance of the SC given Scalia was hard right wanted to nominate someone who would maintain some balance in the SC with a candidate like Garland. The Republican majority wouldn't have any of it, blocked it regardless of qualification and had HRC won probably would've continued blocking appointments forcing the Dems to change the rules again so they could scream foul again and champion themselves as the good guys.
