Trump Catches Obama


For many years, Rasmussen Reports has published a daily poll of likely voters’ views of the incumbent president. Respondents are asked if they approve or disapprove the performance of the incumbent, and whether their approval or disapproval is strong. Rasmussen derives a presidential approval rating for each polling day by subtracting the percentage of respondents who strongly disapprove from the percentage who strongly approve. The complete polling history for Obama is here; the polling history for Trump, to date, is here.

The following graph shows, by day of presidency, the approval ratings for Obama (blue line) and Trump (red line). The difference between the two — Obama’s rating minus Trump’s rating — is plotted as a black line. Obama was well ahead of Trump for about 200 days. Trump has since closed the gap, and is now slightly more popular (or less unpopular) than Obama was at this stage (the 336th  350th day).
