President Donald Trump’s plunging ratings threaten to drag down Republicans in November’s midterm elections, as voters blame him for high prices and a shaky economy, according to a new NBC News poll.

The president’s approval rating stands at 41% among registered voters, a second-term low in the poll, with a majority (55%) of voters saying they believe Trump’s policies have hurt the economy. That’s up from 48% in March, before the Iran war pushed up prices on gas and other goods and cemented the rising cost of living as voters’ most pressing issue.

Democrats hold a 5-point edge in the battle for control of Congress, 50%-45% — a lead, not nearly as large a lead as the 12-point advantage the party enjoyed at this point before the 2018 election, when Democrats rode an anti-Trump wave to the House majority in his first midterm as president. Despite that lead, the Democratic Party is still viewed more negatively than Trump and the GOP.
