Staunch conservatives take leadership positions in GOP-led state legislature • South Dakota Searchlight

A group of staunchly conservative Republicans claimed control of key leadership positions in the state Legislature on Friday evening. 

The leadership election in Pierre marked a consolidation of power for the faction, which has pushed for a more conservative agenda, including bills to regulate minors’ access to online pornography, curtail a controversial carbon capture pipeline, and cap property taxes. 

Those stances have gained traction within the party’s conservative base, especially in rural and eastern parts of the state where the carbon pipeline has been a divisive issue. The proposed project from Summit Carbon Solutions would capture carbon produced by Midwest ethanol plants and ship it to North Dakota for underground sequestration. 

Pipeline opponents ousted 11 of the 14 incumbents who lost seats in the June primary. Those incumbents had voted for a bill that was dubbed the “Landowner Bill of Rights” by its supporters, but was seen as a pro-pipeline law by landowner activists. Opponents petitioned the law onto the general election ballot, and voters soundly rejected it on Election Day.
