Numbers USA has added Texas Gov. Rick Perry to its grid of presidential candidates, giving him an initial grade of D minus. He can bring this grade up significantly, because there are a number of areas about which he’s never taken a position, but his stated positions are mediocre — he’s opposed to sanctuary cities, which is good, and talks a good game in support of border security, but is apparently opposed to E-Verify and has supported (before the recession) increased importation of foreign workers.

Despite the low grade, Perry’s actually in the middle of the pack, with Bachmann, Pawlenty, and Cain at the top, and Santorum, Johnson, and Paul at the bottom. (That’s the spread for the GOP hopefuls — the president is at rock bottom with an F minus.)
