The Constitution, something Biden knows nothing about, invests the authority in the president and Senate to nominate and approve said candidate. PERIOD.
Having an odd number eliminates the possibility of a tie. It is no guarantee for outcome, as is evidenced by the number of votes by Bush appointee John Roberts, who has sided with the liberals and destroyed the Republican expectations of outcomes over and over again.
But mountainjoe, I do NOT understand how you think Trump fears losing and that is the ONLY reason to expedite the nomination through the Senate. Clearly, you have never held public office. When elected to public office, you learn to take nothing for granted. You get done what you can, and you usually don't screw around. I seriously doubt President Trump is overly concerned about losing to Joe Clueless.
The possibility exists the Republicans could lose the Senate majority, and if they vote after the November election, the Dems might find an Obama or Clinton judge that rules the nomination is not valid. The Dem judges are that corrupt, and it is possible the decision is not overturned. I have had repeal judges rule with the decision not because it was right, but because they trust the idiot judge that made the decision. I have ZERO respect for any lawyer, and particularly judges.
