“How is it a 1 Seat majority if the GOP has 217 and the Dems have 213?”
If one GOP member defects on a vote, it would be 216 to 214.
If two GOP members vote with the Dems, the vote would 215 to 215.
According to House rules, in the case of a tie vote, a question before the chamber “shall be lost.”
So just think of the scenario of if a Bill was before the House to fund the building of the border wall. If more than one GOP member votes “nay” then the bill would not pass.
That’s not going to happen anyway. The D3ms got the bill they wanted already.
