ST. PAUL (AP) - Former state House Minority Leader Marty Seifert is putting another campaign for Minnesota governor in motion.

The 41-year-old was declaring his campaign Thursday during a three-stop tour. The Marshall Republican has been out of elective office for almost three years since falling short of his party's nod for governor in in 2010. He joins a handful of GOP candidates vying to take on Democratic Gov. Mark Dayton next year.

Seifert had been considering a campaign for months and finished second as a write-in during a recent straw poll at a state GOP meeting.

Republicans will meet at their state convention in May to consider endorsing a candidate. But that person will almost certainly face an August primary challenge.

Dayton is aiming for a second term.
