What are some famous tie or close votes?

Brexit.

My knee jerk reaction is to say trump / Clinton, but it was neither a tie nor close.

Andrew Johnson’s impeachment trial was one vote short of removal from office.

The Nineteenth Amendment was passed by the House of Representatives with one vote to spare, then sent to the states, where Tennessee was the last state to ratify, and barley passed it by one vote.

Somebody been googling!

No, @Dutchess_lll , I knew that.

Last night’s Commons’ vote to prevent a no-deal Brexit passed by one vote.
