Jensen attracted attention nationally for his assertion in an interview with the Rapid City Journal that the free market, not government, should be allowed to decide whether or not racial discrimination is acceptable, and that his SB 128 introduced in 2013, which would allow discrimination by business owners, would serve to protect "the constitutional right to free association, the right to free speech and private property rights." (The bill failed, having drawn such reactions as fellow Republican State Senator Mark Kirkeby terming it "a mean, nasty, hateful, vindictive bill.")[4] Jensen's stance was repudiated by Republican Governor Dennis Daugaard, who issued a press release stating, "I found his comments to be completely out of line with South Dakota values. I don't agree with him and I haven't talked to anyone who does.[5] Jensen is uncertain about the assertion that he is South Dakota's most conservative politician, describing himself as simply a true Reagan conservative; but asserts that "too many" members of his own party are Republicans In Name Only.[6]
In 2022, it emerged that Jensen had been a member of the far-right militia group, the Oath Keepers.[7]

2012 When incumbent Senate District 33 Republican Senator Elizabeth Kraus left the Legislature and left the District 33 seat open, Jensen ran in the June 5, 2012 Republican Primary and placed first with 1,128 votes (57.6%) against former Representative Michael Buckingham[12] who had run for the seat in 2008; Jensen won the November 6, 2012 General election with 5,722 votes (57.4%) against Democratic nominee Matt McGrath.[13]
