The tipping point state is computed by sorting all the electoral college votes (assuming no faithless electors) by the % margin and finding the one that, given a uniform percentage swing, would have tipped the election.
If the tipping point is at the boundary of two states then those states are considered to have tied for being the tipping point. In this situation a uniform swing could have caused an electoral college tie.
