Republicans are slated to squared off in a handful of competitive state legislative primary contests on August 10. In most instances, the GOP rivals are vying to take on a DFL incumbent in districts that look winnable.

The power divide between DFLers and Republicans in the Minnesota House may look daunting on its face, but not so long ago the GOP held a similarly imposing majority.

If it’s possible to judge a legislator’s re-election vulnerability solely on the number of challengers that he or she attracts, then Lisa Fobbe, Jim Carlson and Kevin Dahle should probably watch their backs.

Minnesota Republicans, buoyed by national congressional gains and an increasing tide of conservative sentiment, are queueing up to challenge incumbent DFL state legislators this year.
