If there was ever a submission that epitomizes "should not be on HN" I think this might be it. If the person who submitted this is reading the comments I'd ask them to please tell me what justification they were using in their head for this.
Visualization of data tends to be pretty interesting to a lot of us. While yes, the original post is a trite joke about Fox News, it's interesting to look beyond it to the graph itself and wonder how you would show that data in a smarter way. Venn diagram?

You could back more than one candidate.
That doesn't justify a pie chart (3D pie chart, no less!) with amounts in percentages that add up to 193%

I think the problem is not that you can back more than one candidate but simply that a pie chart is not really the appropriate vehicle to present the data.
I've never seen a pie with more than 100% pie in it...
