Question of the Evening

I came across this chart of 2008 candidates' positions via BoingBoing. It has a large matrix of candidates and issues with checkmarks for positions they support and X's for things they oppose. But for former Governor Mitt Romney, they had to invent a new icon -- an x'ed out check -- for his position on reproductive choice. Given that they'd already invented one symbol for Mitt, why not give him double the checkmarks under the Guantanamo category?
