Even if every Republican Senator vote NOT to confirm Levine, it won’t matter, Kamala Harris can cast the tie breaking vote.
Unfortunately, I can see at least 3 or 4 Republicans who WILL vote to confirm her so, Kamala’s vote won’t be needed.
Worse, the same situation with Joe and Kamala applies here: while s/he may be confirmed as the Assistant, the top dog will soon be pushed out and s/he will ascend as the Cabinet Secretary.
