Mail in ballots in the vote for the US Senate in Nevada will pay a crucial role for Democrats to control the Senate. Some reports say Democrats who are running at about 61% in mail in ballots could make it through if they get 55% to give Ms. Cortez Masto the Democrat a seat in the Senate. With Arizona leaning Democrat this would give the Democrats control of the Senate even before the runoff election in the third undecided state of Georgia in December. So close has been the struggle for the US Senate.
