US President Donald Trump’s approval rating has fallen to 33%, while Democrats have gained an advantage in national congressional preferences ahead of the November midterm elections, according to a Washington Post-ABC News-Ipsos poll. Rising living costs, dissatisfaction with the economy and concerns about the administration’s policies are emerging as key issues for voters. The midterms will determine control of the US House of Representatives and Senate, shaping Trump’s ability to advance his agenda during the second half of his term.
