Voters who view immigration as the biggest crisis mostly back rightwing parties such as the National Rally in France or Germany’s Alternative für Deutschland (AfD); those who prioritise the climate tend to support green or leftist parties such as Spain’s Socialists or Poland’s Left.
This seems like a misrepresentation. It is not as if the followers of right-wing parties see the climate crisis as the smaller problem, they usually outright deny its existence and want to sabotage any attempts to limit its impact by actively favouring fossil fuels and other technologies harmful for the climate.
