In the Senate, a quorum is a majority of the body, so 51 members may do the business of the Senate.
So, 35 members is 2/3 majority in the Senate with a minimum quorum.
I wish it were 35 members, that would be one more vote he would have to get. It would actually be 66 2/3% of 51 which is:
51 x .666666 = 33.999966 or 34 members
You’re right. I used 51*.67
If I had stayed in fractions, 51*2 / 3 it is exactly 34.
