Jens Spahn, CDU
The 38-year-old is the youngest and most overtly determined Merkel usurper. He entered the Bundestag in 2002 and became Germany's health minister in 2018. Spahn, who is openly gay, is popular in the CDU's conservative wing. He opposes limited dual citizenship for young foreigners, criticized attempts to loosen laws on advertising abortions and called for banning the Burqa in public.
