Joe Biden vs Paul Ryan ratings
Biden’s rating includes votes from the 2008 election comparison so it’s not going to be an apples-to-apples comparison with Paul Ryan immediately. This snapshot is a good indication of their starting scores so when we examine their ratings a few months from now we’ll know how each candidate did.
Behavioral psychologists will tell you (and we would too) to take these ratings with a pinch of salt. Biden performed well because in the last election he was being compared to Palin. His ratings would most likely have been lower if people were rating him on a page that compared him to Obama instead. So making note of this starting line is important because come November, we’ll be able to do a more accurate head-to-head comparison of Ryan with Biden, without letting Biden take advantage of his former comparison with Palin.
