The ABC News/Washington Post poll shows 22% of voters are still "persuadable" - meaning they are anxious about the candidate they support. That total is virtually split between Mitt Romney and Barack Obama voters.
Persuadables are middle-of-the-road types, making it difficult for the candidates to reach them with traditional red-meat appeals to core supporters. For instance, among registered voters who don't feel strongly about Obama's work in office (i.e., saying they "somewhat" approve or disapprove), 37 percent are persuadable. That dives to 15 percent among those who feel strongly about Obama, either pro or con.
Similarly, this analysis, produced for ABC by Langer Research Associates, finds that 26 percent of political moderates or "somewhat" conservatives are persuadable, compared with 16 percent of liberals and "very" conservatives. And while 19 percent of those who currently are "enthusiastic" about their preferred candidate are persuadable, that rises to 36 percent of those who support a candidate, but not enthusiastically.
Among other groups, persuadability is now lowest, by partisanship, among Democrats (16 percent) and highest among independents (26 percent). There was no movement in persuadability pre-and post-convention among independents, customarily a swing voter group.
