60-40 would be great for the GOP. And Bush won 51-48 nationally.
It would be great, and even in the biggest wave year for either party in decades Perry couldn't even get to the George W Bush level of support in the hispanic community. Bush over-performed with the hispanic vote and only lost it by 10 percentage points nationally, had he lost it by 20 points it could have been enough to change that outcome. Don't worry, that 20 point margin will go up to 25 or more in 2012.
Edit: I got my numbers wrong. According to CNN exit polls Perry lost the Hispanic vote 61-38. In 2010 McCain lost it 63-35. Meaning in the best GOP election cycle in decades the GOP only shifted the vote by about 3 points or less. Perry is weak there and it could cost him in the west.
