When does the recount have to be complete? Thanks.
Technically, it NEVER has to be completed!
The legislature can appoint the Electors themselves if neccessary.
“2: Each State shall appoint, in such Manner as the Legislature thereof may direct, a Number of Electors, equal to the whole Number of Senators and Representatives to which the State may be entitled in the Congress: but no Senator or Representative, or Person holding an Office of Trust or Profit under the United States, shall be appointed an Elector.”
Now, in practice... the Electors meet on *December 19th* this year to cast their votes. So it should be done before then.
