Poll: iPhone owners support Obama

Android and iPhone users accounted for about 36 percent of all respondents to the survey.

“The results of this survey demonstrate that the smartphone market is becoming a whole new demographic that candidates must take into consideration when building a comprehensive campaign strategy,” said Krishna Subramanian, chief marketing officer for Velti.

He argued that candidates should do more to advertise to smartphone users.

Romney does lead Obama among retired iPhone and Android users 57 percent to 34 percent, according to the poll.
