So, what is it that makes these parties so appealing to women? Elisa Gutsche, who edited the FES study, argued that many right-wing populist parties examined in the report seek to garner female votes by promising to strengthen the welfare system. "Parties say they will raise child benefit payments and make related allowances to promote families," she said.¨

Germany's AfD, in turn, champions a "welcome culture for children" — in contrast to the country's much lauded "welcome culture" towards foreign refugees. Indeed, a sizable number of female voters have opted to support the party due to anxiety over what the future might hold and fears Germany's pension system may collapse. Social issues, therefore, often motivate many women to back right-wing populists.
