Answer: A
Explanation:
Senator Edmund Ross of Kansas cast the deciding vote, and for all purposes, he was expected to vote against Johnson, up until the night before the final roll call.
The answer is A. Edmund Ross (he represented Kansas)
Jefferson Davis was the president for the Confederate states
Thaddeus Stevens was part of the House of Representatives not the Congress, therefore he wasn't a senator
Abraham Lincoln didn't have a say in matters like this because he was the president before Johnson and didn't have any power anymore. He also couldn't have done anything in this situation because he's DEAD
Hope this helped!
