– President Obama is crossing South Dakota off his list.

The home of Mount Rushmore and the Badlands is the last state to get a presidential visit from Obama. He said in an interview with South Dakota station KSFY-TV that he will deliver the 2015 commencement address at Lake Area Technical Institute in Watertown next month. Commencement is May 8 at the Watertown Civic Arena.

Obama cited the school's strong graduation rate as a reason he decided to visit.

Obama campaigned in the state as a candidate during the 2008 election, stopping at Mount Rushmore.

The president has been crisscrossing the country since the start of this year to promote his economic policies, stopping in some of the GOP-leaning states that he hadn't visited during his first six years in office. Idaho, South Carolina and Utah have all hosted — for the first time — the president in recent months.

He will be the fourth president to visit all 50 of the states while in office. Ronald Reagan was first; George H.W. Bush and Bill Clinton also did it.
