[2] As chair of the Youth League, she became known for several high-profile statements, including her criticism of the Moderate Party’s refugee policy, where she advocated for a significantly more liberal approach,[3] as well as her proposal for privatized prison services.

However, the senior party leadership blamed the election loss partly on Lifvendahl, arguing that the Youth League’s proposals had alienated voters.

[7] After Lifvendahl's resignation from MUF in 2002 she became the first Moderate Youth League chairman to be re-elected to the board of the party on her own mandate, a position she left in 2005.

[8] When she requested to be relieved of her duties she cited a desire to focus more deeply on some of the party’s policy areas, which would leave her with insufficient time for the board position.

In the spring of 2000, Lifvendahl became a columnist for Svenska Dagbladet and worked as a substitute editorial writer during the summer, writing opinion pieces on topics such as crime victims, the Swedish Agency for Youth and Civil Society, and the documentary Shocking Truth.

After stepping down as chair of the Moderate Youth League in 2002,[9] she began working part-time as a communications consultant for the firm JKL in Stockholm.
