US President Donald Trump’s approval rating has fallen to 31%, the lowest level of either of his presidential terms, as rising petrol prices and concerns over the economy weigh on American voters ahead of the November 3 midterm elections. A new Reuters/Ipsos poll also shows Democrats opening up a 12-point lead over Republicans in the race for control of Congress. The poll, which closed on Monday, October 19, found that 47% of registered voters would vote for a Democratic candidate if congressional elections were held today, compared with 35% who would choose a Republican.
