US President Donald Trump’s net approval in analyst Nate Silver’s aggregate of US national polls slid two points in the last week to -9.4, after his ratings had been stable since late July. Currently, 53.1% disapprove of his performance, compared to 43.7% who approve. Trump’s net approval was worse last Wednesday at -10.0 before recovering. This is only slightly better than his worst net approval of this term, -10.3 on July 22. In Silver’s historic approval data, Trump’s ratings are worse than any other president after Harry Truman – they only top his own ratings at this stage of his first term.Trump’s ratings may have slid over his administration’s controversial attempts to cancel the late-night television host Jimmy Kimmel. Analyst G. Elliott Morris cited a YouGov poll this week in which 68% of Americans said it was unacceptable for the government to pressure broadcasters to remove shows it disagrees with, compared to just 12% who said it was acceptable.An alternative explanation for the slide in Trump’s ratings is inflation. Silver tracks Trump’s ratings on four issues: immigration, the economy, trade and inflation. Trump’s net approval on immigration (-5.3), the economy (-15.6) and trade (-17.3) have held up in the last month, but his net approval on inflation (-30.0) has dropped six points since the end of August.The benchmark US S&P 500 stock index peaked last Monday at nearly 6,700 points, an increase of 2.8% in the last month. I believe Trump’s ratings are unlikely to become very poor unless something goes badly wrong with either the stock market or the broader US economy.US and UK elections and pollsLast Tuesday, Democrats held Arizona’s seventh House district in a US special election, with a substantial swing in their favour. Other US state and local elections will happen on November 4, covered here in The Poll Bludger.There will also be a deputy Labour leadership election in the United Kingdom in late October.
