Merkel was reelected because there was no feasible Alternative. She is a good politican with proper experience and Connections especially on the international stage, But her politics is as shit AS the rest. One of the reasons why right wing parties are on the up. Think of her as the equivalent to biden. The only thing she has going is that one can assume with certainty she is not gonna fuck shit up so hard, but there are certainly better ways. Fun fact: merkel actually announced she would not be up for re-election in 2021.
