Make a box for each state, sized proportionate to its electoral votes, sort them by political leaning, and glue them end to end. A point in the middle shows the electoral vote cutoff, and the states nearest it are the ones that'd be easiest to sway one way or the other. The chart is a giant line that's like six screens across, so make it zig-zag to fit on a screen. Call it a snake chart and pretend that's clever so people don't realize how lazy that zig-zag part was.

That might be easier to understand for those already familiar with bar charts but it's uncreative.
Are you familiar with this chart of Napoleons invasion of Russia
It's not super intuitive but once you grok it, it is a brilliant representation of the campaign in a way that bar charts cannot approach.
I think the snake part is a reference to Join or Die
