She is the leader of the party since 25 April 2015, and also a councillor in opposition in Uppsala municipality. Growing up in Gunsta, near Uppsala, she was a student at the Christian Livets Ord primary school. In 2009 she assumed responsibility for the budget when Essen went on sick leave, and at the age of 22 she became a substitute municipal councillor.
The party youth organization chairman Charlie Weimers, who did not get to vote in the election, wrote that he thought the party should have Busch Thor at the top of the ballot.
In the end, a closed vote within the party decided the top name on the ballot, and Busch Thor beat Essen by a margin of two votes. At the election, Busch Thor received 1,679 votes, against only 220 for Essen.
Busch Thor served as vice chairman of the Christian Democrat youth organisation until 5 June 2011. Busch Thor made several comments to the media during 2010 criticizing the then party chairman Göran Hägglund, and what she perceived as his weak leadership following the 2006 General Election.
She was also herself a candidate for the post of deputy party chairman at the same election, but lost to Maria Larsson.
In 2015 Busch Thor was announced as the suggested successor of Göran Hägglund as party leader of the Christian Democratic party, and was formally elected on 25 April.
Busch Thor was the municipal party political secretary for the Christian Democrats councillor Gustaf von Essen in the Uppsala Municipality. Ahead of the election for municipal councillors in Uppsala in 2010, the party suggested that Busch Thor should be placed third on the election ballot, while the incumbent councillor Gustav von Essen would be first.
