Concerns, exploitation of mentally disabled voters or DNC gets out the base Jimmy Green's stepdaughter had never voted before. The 57-year-old is mentally disabled, and Green said she doesn't understand the concept of casting a ballot. But this week, she called her parents to say she had voted for President Obama. The care home in Fayetteville where she lives registered its residents to vote and drove them to the polls, Green said. "My concern is that somebody told her who to vote for," he said. "She didn't even know there's two different parties." Complaints of uncomprehending voters being ferried to cast ballots surface every election. And in a presidential race as close as this year's, with huge levels of early voting, any perceived irregularity is falling under intense scrutiny.
