There are remarkable differences in how Republican voters view Mitt Romney and Sarah Palin based on their class and education level.
Among Republicans who make less than 25k a year 73% view Palin favorably but only 38% say they like Romney. Expand that to less than 50k a year and the gap closes but is still pretty wide- 75% with a positive opinion of Palin to 46% for Romney.
At the top of the pay scale it's a different story. Among GOP voters who make 75k on up the two are equally popular, with each seen positively by 66%. And when you restrict it those who make over 100k, Romney becomes the more popular one at 74% to Palin's 61%.
The divide is even wider on education level, at least at the low end. Among Republicans who have no schooling beyond high school 78% view Palin favorably while only 29% have a positive opinion of Romney. Expand that group to people who have some college education short of a four year degree and the gap narrows a little bit but remains wide at 72% favorable for Palin and 45% for Romney.
If Romney's going to win the nomination in 2012 he probably has to convince downscale GOP voters that he understands and shares their values and isn't just some rich guy who was born with a silver spoon in his mouth. And Palin's going to need to be able to convince wealthier Republicans that she's not just a social conservative, but also someone who can bring good leadership to the table that helps businesses and the economy.
