ST. PAUL — Minnesota Lt. Gov. Yvonne Prettner Solon, who once parachuted to the Capitol lawn from 12,500 feet up, said Tuesday she won’t join Gov. Mark Dayton in his bid for a second term.

Prettner Solon said she will finish the final year of this term.

Prettner Solon brought northern Minnesota appeal to Dayton’s campaign in 2010. His calculations for a running mate in 2014 will be different because he doesn’t have to worry about a primary where geographic diversity of his ticket mattered more.

Possible successors include the leader of the state’s Iron Range development agency, former state Rep. Tony Sertich; Assistant Senate Majority Leader Sen. Katie Sieben of Newport; and Dayton chief of staff Tina Smith. Dayton could also go outside government for his pick. He has until early June to decide, though aides expect the process to move faster.

Prettner Solon, 67, built a decade-long career in state government after spending many more years on the periphery. When she joined Dayton’s ticket in 2010, Prettner Solon was in her third term as a state senator from Duluth after assuming the seat held by her husband, Sam, up until his death.
