Correction: During the first White House press conference after Donald Trump won the US presidential election in November 2016, President Obama stated that “elections matter”, whereas he stated that “Elections have consequences” soon after his inauguration in January 2009. The two statements have equivalent meaning, but the misquote in the cartoon is regretted.
