Critics of this theory might point out that this new Pew survey is of all Latino adults, and not specifically of voters, meaning that the sample might not reflect the feeling of the electorate. Also, the Pew survey doesn't specifically say whether the increased optimism has translated into greater support for Obama.
But survey after survey has shown that Latino voters trust Obama over Romney on the economy. A separate Pew survey of registered voters released in mid-October showed that 45 percent see the nation heading in the right direction, up nine points from last year. And a recent NBC News/Wall Street Journal/Telemundo poll showed that 63 percent approve of Obama's handling of the economy and believe the president is better equipped to handle the economy than Romney by a 33-percentage-point margin.
Romney's economic message has likely helped him make it a close race among all voters, but it hasn't been the case among Latinos.
