Support Soft for Romney and Obama

Neither one has built up much enthusiasm among supporters

One in four registered voters may be persuadable in the 2012 presidential election – rich pickings if either Barack Obama or newly minted GOP nominee Mitt Romney can win their support. But doing so may be a challenge, requiring both subtle and substantive political persuasion.

That's because persuadable voters, as identified in this analysis for ABC News, are less apt to be ideologically committed ones, and more likely to take middle-ground rather than strongly held positions on issues such as Obama's job performance, Paul Ryan's Medicare plan and their own partisan views.
