AP-Yahoo! News poll, “Changeable voters … 1 in 7 voters still persuadable,” By AP’s Alan Fram: “a stubborn wedge of people, … somehow, are still making up their minds about who should be president. One in seven, or 14 percent, can’t decide or back a candidate but might switch, according to an Associated Press-Yahoo News poll of likely voters released Friday. Who are they? They look a lot like the voters who’ve already locked onto a candidate, though they’re more likely to be white and less likely to be liberal. And they disproportionately backed Hillary Rodham Clinton’s failed run for the Democratic nomination.”
