Are smartphone users really smarter? The answer likely depends on your political views because a new Velti survey has revealed a 20 percent difference between Android and iPhone users' probable voting choices and those of non-smartphone users.

When asked who they would vote for if the presidential election were held today, 49 percent of smartphone users chose the incumbent, President Barack Obama, while just 31 percent selected Republican candidate Mitt Romney.

Meanwhile, traditional polling that doesn't select for gadget use shows a much tighter race, with Obama currently just 2 points up on Romney.

Smartphone users are becoming an entirely new demographic that candidates and advertisers need to consider during campaigns, Velti chief marketing officer Krishna Subramanian said.

"Clearly, mobile advertising is emerging as an influential medium and a distinct audience," she said.

She cited Romney's iAd campaign, which didn't exactly strike the chord the presidential hopeful was aiming for due to an unfortunate spelling error. Despite that foul-up, Subramanian is hoping more political campaigns will try similar marketing tactics, perhaps with a quick spell check.

Most importantly, Subramanian said, is the growing understanding of how important this relatively new demographic is, and what a difference brand awareness and consumer behavior can make when addressing a generation of smartphone users.
