Gore only needed to win FL where the margin was razor-thin.
Hillary would need to flip three states. Yeah, a tall order.
I was living in Florida at that time (thankfully a couple of years later I escaped).
There was a lot of vote fraud. Much of it painfully obvious. So, while I agree the margin was very close, it was not nearly as close as the official tally. In addition to the seemingly endless boxes of ballots discovered in broom closets several Democratic run counties refused to accept military absentee ballots. It was heartbreaking to see elected officials (libs) get on TV with straight faces and shovel their crap about refusing to count military ballots. A lib I had been good friends with for years told me he thought it was great because it might give the state to Gore. That changed our friendship.
PS: I will also never forgive the Republican voters in Florida that walked away from the polls without voting because the networks called the state for Gore. I refused to do that. My vote is going to be counted no matter what.
