For months now, President Trump has trailed Joe Biden in the polls. First, it was only a 5- or 6-percentage-point gap, but since the middle of June, that margin has widened to anywhere from 8 to 9 points, according to FiveThirtyEight’s national polling average.
But until very recently, voters didn’t seem all that convinced that Biden could win. In poll after poll, comparatively more voters said they thought Trump would win reelection in November. Now, though, that view may be shifting.
Over the past two and a half months, the share of voters who said they expect Trump to win has fallen from about 45 percent to around 40 percent in polling by The Economist/YouGov, as the chart below shows, while Biden’s share has slowly ticked up to where Trump’s numbers are. (Roughly a fifth of respondents still say they’re “not sure.”)
Trump’s decline may not seem that dramatic — and it’s not; it’s only a few points lower — but it’s notable because prior to June, he had trailed on this question only once since The Economist/YouGov first asked it in December.1
But it’s not just the Economist/YouGov polling that supports this finding. USA Today/Suffolk University found a more substantial drop in Trump’s numbers. In late June, 41 percent of voters said they expected Trump to win, whereas 50 percent said the same in the pollster’s late October 2019 survey. Conversely, 45 percent said Biden would win in June, an improvement from the 40 percent who picked the Democratic nominee in October. Republican pollster Echelon Insights has also observed a downward trend in Trump’s numbers: In a survey completed last week, 33 percent of likely voters said they expected Trump to win, which was down from 39 percent in the pollster’s June survey. Meanwhile, the share who thought Biden would win ticked up to 43 percent in July from 40 percent in June.
On the whole, it seems voters are now less confident in Trump’s reelection chances, and the main driver of that shift may be independent voters. In USA Today/Suffolk’s June survey, 47 percent of independents picked Biden versus 35 percent who chose Trump, a reversal from the October 2019 poll, when 54 percent of independents expected Trump to win compared with 30 percent who said the Democratic nominee would win. And looking across the Economist/YouGov data since early May, the share of independents who expect Trump to win has slid as well, from the low 40s to the mid-to-high 30s.
As for Democrats and Republicans, they mostly say their respective nominee will win, although that wasn’t always the case in 2016, as many Republicansthought Hillary Clinton would win. Nonetheless, that doesn’t seem to be happening in 2020. The Economist/YouGov and USA Today/Suffolk surveys found that Democratic voters are largely confident in Biden’s chances, while most Republicans believe that Trump will win. However, since May, the Economist/YouGov polls show an increase in Democrats’ belief in Biden’s chances and a slight downtick in Republicans’ faith in Trump’s.
