Minnesota legislative races, long low-dollar affairs, have exploded into six-figure contests, with campaign spending for House and Senate seats doubling over the past decade.
Examining data from every legislative race for that period, the Star Tribune found that candidates, parties and political action committees spent nearly $24 million on Minnesota's House and Senate races in 2012. In 2002, that figure was less than $12 million.
Until 2012, only two legislative races — both in 2006 — had ever topped $500,000 in Minnesota for election spending. Last year, nine legislative races passed that milestone, while another 29 came in at more than $200,000.
In Minnesota and across the nation, legislative races are shattering all previous spending records as political groups pool their cash and bring their best data, staffing and technical resources to bear in statehouse districts.
Much of that is driven not by the candidates, but by political action committees and parties.
The choice for political interests is clear: They can spend millions on high-stakes congressional races, win a few seats and still see Congress mired in gridlock. Spend those millions on legislative contests, and they can get quick change and massive state-by-state results.
Partly because of this shift in strategy, more state Capitols are controlled by a single party than at any time in modern history.
"You can take that same amount of money and you can, literally, as we saw here in Minnesota, flip entire legislatures in one election cycle," said Keith Downey, chairman of the Minnesota Republican Party.
