Gov. Mark Dayton is raising campaign cash in Washington this week as he tries to keep a financial advantage over his Republican opponent, Jeff Johnson.

Dayton and running mate Tina Smith traveled to Washington Monday. They're appearing at an evening fundraising reception at a private home, with contributors urged to give $1,000, $500 and $250. Sen. Amy Klobuchar is also appearing at the fundraiser.

Also on Dayton's schedule is a Tuesday morning fundraiser at D.C. lobbying firm Forbes-Tate, also with Klobuchar in tow. That one has higher suggested donations of $2,000, $1,000 or $500.

Throughout the summer Dayton maintained a significant fundraising advantage over Johnson, whose primary campaign left him with little money in the bank by mid-August. Johnson has said he's spent large amount of times on fundraising since then.

The next snapshot of the candidates' fundraising progress comes at the end of September, which will give a sense of whether Johnson has made any progress toward closing the gap.

Johnson campaigned in southwestern Minnesota on Monday morning, including at several events with his primary opponent Marty Seifert.
