Martinez was elected Governor 53-47 in 2010, and we find her leading challenger Gary King 47-42. Martinez has a 52/40 approval rating, largely consistent with where we've found her since she took office. She overcomes the strong Democratic advantage in the state by winning independents almost 2:1 at 53/27, and getting 24% crossover support from Democrats.
Martinez has wider leads over all the rest of the Democrats in the race. It's 11 points over Lawrence Rael at 47/36, 14 points over Howie Morales and Linda Lopez at 48/34 and 50/36 respectively, and 16 points over Alan Webber at 48/32. King starts out as the pretty strong favorite to be the Democratic nominee though. He leads the primary field by over 20 points, getting 34% right now to 15% for Morales, 13% for Lopez, 7% for Rael, and 5% for Webber.
