Faced with a sprawling global crisis, world leaders have begun setting policies into motion that will have vast economic and health implications, and will almost certainly play an outsized role in defining their legacies. The coronavirus outbreak has already shifted the political terrain in a number of countries, swiftly impacting how heads of state are viewed by their constituents, as new Morning Consult Political Intelligence data illustrates.

British Prime Minister Boris Johnson has had the most dramatic shift in fortune: his net approval rating has risen by nearly 30 points in a matter of days. French President Emmanuel Macron, German Chancellor Angela Merkel, Canadian Prime Minister Justin Trudeau, and Australian Prime Minister Scott Morrison have all had their net approval rating increase by double digits since March 11, when the World Health Organization (WHO) declared the coronavirus to be a global pandemic.

The data stems from daily approval tracking in nine countries, with between 315 and 616 survey interviews in each country per day, released in seven-day rolling averages. In the United States, results are based on an average of 7,126 daily interviews with U.S. adults (Note: Morning Consult’s Trump approval rating releases are typically among registered voters).
