The National Party Congress of Germany’s ruling Christian Democratic Union will be held online from 15 to 16. The most important agenda is to elect a new party chairman. According to the current political situation in Germany, the new president of CDU is likely to succeed Merkel and become the next German Chancellor. < / P > < p > at the end of October 2018, Merkel, who is in her fourth term as prime minister, announced that she will no longer seek to serve as the chairman of the CDU and will no longer run for the Federal Chancellor in the future. The CDU started the process of leadership transition. < / P > < p > originally, after Kramp kalenbauer, who was supported by Merkel, was elected as the party chairman at the National Congress of the CDU in December 2018, the party handover should have ended. However, due to the tumultuous turlingen governor election, Kramp kalenbauer announced his resignation as the party chairman in February 2020, which led to the recurrence of the successor problem. < / P > < p > Germany will hold the Bundestag election in September this year. According to the opinion poll, the support rate of the CDU remains above 35%, ranking the first, 17 percentage points higher than that of the second green party. If nothing happens, CDU will maintain its position as the largest party in parliament after the election of the Bundestag. < / P > < p > according to the tradition of the CDU, the party chairman is also the party’s candidate for prime minister. According to the German political system, the largest party in the Bundestag will take the lead in forming a cabinet, and its candidate for prime minister will become the new prime minister. Therefore, the new party chairman elected at the CDU Congress is likely to become the new German prime minister after the election of the Bundestag. < / P > < p > Raschet, 59, is the governor of the population and industrial state of North Rhine Westfalen. German media’s evaluation of him is “the golden mean”. Raschet’s policy is not very different from Merkel’s. He once supported Merkel’s decision to accept refugees during the European refugee crisis, and he also said that he would maintain the continuity of the policy. But covid-19 is considered to have failed to cope with the new crown disease in North Wei, especially in the early stages of the outbreak, but the implementation of the Rast restriction measures is not strong enough. < / P > < p > Mertz, 65, a lawyer, is running for the second party chairman. He once served as the chairman of the coalition party in the Bundestag, which is composed of the CDU and its sister party, the Christian Social Union. Later, he disagreed with Merkel and went into business in 2009. After Merkel announced her retirement, he soon returned to politics. Mertz has attracted the support of some more conservative members of the CDU with his conservative remarks, and the attitude towards him in the party is seriously polarized. < / P > < p > letgen, 55, was a former German environment minister. Later, she was criticized by Merkel for leading the CDU horn in the North Wales parliamentary election in 2012, and was removed from her post. He served as chairman of the Foreign Affairs Committee of the Bundestag since 2014. Lotegan is an environmentalist with an image of youth and reform. < / P > < p > according to the public opinion survey, the support rate of the above three popular candidates is very close at present, murtz is 29%, and the other two are 25%. Among the economic elites, Mertz has a big lead in the support rate, while in the top political circles, Raschet is relatively more popular. Public opinion believes that in view of the small support gap among the three people, the election should be conducted in two rounds. The one with the lowest vote in the first round will be eliminated, and the final winner will be decided in the second round. < / P > < p > according to the agenda of the Party Congress, the election of the new president is scheduled for the 16th, but because it is held online, some delegates will vote by mail, so the final result will be announced on the 22nd. However, all three candidates said they would accept the result of online voting because they thought that if they lost the online voting, no one would vote for them by mail. This statement means that the election results may be known on the 16th. < / P > < p > however, the development of the situation has brought new possibilities. The new chairman of the CDU party does not necessarily become a candidate for prime minister. Mertz and letgen said that the candidate for prime minister may also come from the basic social League. Marcus Zede, President of the basic social League and governor of Bavaria, took strong measures to control the epidemic, which was very eye-catching. Some polls show that he has a high approval rating as the candidate for prime minister, second only to Merkel. Some analysts believe that although Zeder said he would stay in Bavaria in the summer of 2020, if there is a more attractive prime minister, he is likely to be attracted. < p > < p > in addition, German health minister Jens Shipan, who has been confirmed in the epidemic, is also considering competing for the post of prime minister on behalf of the CDU. The 40 year old has made no secret of his ambition to become prime minister, but he still supports Raschet.
