South Dakota Senate Democratic leader Billie Sutton says he raised more than $870,000 for his governor campaign in 2017.

Sutton announced fundraising numbers Monday in his bid to succeed Republican Gov. Dennis Daugaard. Sutton's campaign says he ended the year with roughly $664,000 in the bank.

The campaign says Sutton has outperformed other Democratic candidates for governor at this stage of the race. The lawmaker from Burke wants to become the first Democratic governor elected in South Dakota since 1974.

U.S. Rep. Kristi Noem and Attorney General Marty Jackley are Republicans competing for the governor's office in 2018.

Jackley's campaign announced earlier in January that he'd raised over $1 million in 2017, but didn't give specific numbers.

The deadline to submit year-end campaign finance reports is Friday.
