Mitt Romney is now widely said to be "surging" in the Presidential polls, although that does seem a little excitable—he's only 0.8% ahead of Barack Obama in today's RealClearPolitics Average. Still, several polls do show him slightly ahead.

Romney's white share still seems stalled in the post-Reagan Bush-McCain range. There is still no sign he will even match the 60% share achieved by GOP Congressional candidates in 2010. (More white share comparisons here—scroll down).
