Something I noticed the other day from a Discord conversation on Spanish politics was this.
Felipe González was the 3rd democratic PM of Spain. He became leader of the Socialist Party in 1974; first ran for election in 1977 (the first democratic election in Spain since the 2nd Republic). He won in 1982 and ruled for 4 terms until 1996 when he finally lost.
Gonzalez was also born the same year as Joe Biden.
Although in fairness to Biden, he was elected to the Senate for the first time in 1972, so he had an even earlier start to his career. Still his career has been quite long, most people his age would have already retired.
Giovanni Goria, born one year later than Joe Biden, was Head of Government in Italy from 1987 to 1988.
Sadly he died in 1994 from lung cancer.
