An overwhelming majority of Americans reject Karl Rove's attempt to scandalize Hillary Clinton's health and age, according to a new poll.

Rove has suggested in several appearances this month that Clinton's age and health should be major issues if she chooses to run for president, baselessly speculating that a concussion she suffered in December 2012 could have long-term repercussions. Rove's smears were echoed by his Fox News colleagues and others in the conservative media but termed a "lie" and "dirty tricks" elsewhere.

According to polling released today by ABC News and the Washington Post, 66 percent of Americans disapprove of Rove's attack, “including 46 percent of Republicans and 43 percent of strong conservatives.”

Rove's former colleagues in the Bush administration have termed his comments a deliberate effort to start a conversation that damages Clinton. That effort isn't working.
