The Angela Merkel era is ending. Currently, there are three candidates are vying for her position. The cast of characters is interesting: The ambitious Jens Spahn, currently serving as health minister; the woman generally viewed as Merkel’s anointed heir and perhaps a kind of Merkel 2.0, Annegret Kramp-Karrenbauer, and Friedrich Merz, an old arch rival of Merkel’s who abandoned politics for finance after he was elbowed out by her in 2002.
