Americans have further soured on Vice President Kamala Harris as she continues her radio silence on the chaotic and tragic withdrawal of US forces from Afghanistan, a new poll indicates. According to a Rasmussen Reports survey released Thursday, 55 percent of likely voters say the former senator from California is either “not qualified” or “not at all qualified” to assume the duties of the presidency. By contrast, 43 percent consider Harris “qualified” or “very qualified” to be commander in chief. The same poll found in April that 49 percent of likely voters said Harris was qualified to become president, though 51 percent of voters had an “unfavorable impression” of her. The poll was taken between Aug. 12 and Aug. 15, as the Taliban embarked on its sweeping offensive across Afghanistan that led to the collapse of that country’s Western-backed government weeks before the deadline to remove US combat forces. Harris has not held a public event since last week, when she cut short a meeting with CEOs to discuss the Biden administration’s childcare proposals in order to receive an intelligence briefing about Afghanistan.
