During his teenaged years, he was active in the Center Party's Youth Organisation (CUF).^[4] The issues he considered most important at the time were the fight against apartheid and the opposition to nuclear power and the Social Democrats' relocation policy. He ended his time at CUF by being the union's first vice president between 1987 and 1989.

During the period 1989–1993, Jonsson was chairman of the National Council of Swedish Youth Organizations, LSU (Landsrådet för Sveriges Ungdomsorganisationer [sv]). Jonsson's political involvement then continued in the Center Party as a member of the municipal council and for nine years as district chairman in Gävleborg County.

In the 2010 parliamentary elections, Jonsson was elected to the Swedish Parliament and took a seat on the Riksdag's Health and Welfare Committee. He is also a member of the National Audit Office's board and a deputy on the Social Insurance Committee. His political interests mainly concern entrepreneurship, child policy, and healthcare.

He was also chairman of the renewal group tasked with working on a renewed welfare policy.

Jonsson was one out of three main candidates to take over the position as the party leader of the Center Party during the party meeting in Åre in September 2011.^[5] On 31 December 2011 Annie Lööf was nominated, and Jonsson took back his candidacy.^[6] At the meeting he was elected as vice-party leader.
