An expensive Democratic primary is brewing in Minnesota’s 6th Congressional dDstrict, with two well-funded would-be challengers moving towards a showdown to take on Republican Michele Bachmann.

The party establishment favorite, state Sen. Tarryl Clark, announced Monday that she has raised in impressive $308,000 since declaring her candidacy July 28. The campaign will report just under $270,000 in the bank at the end of September.

Physician Maureen Reed, Clark’s rival for the Democratic nomination, announced a $130,000 fundraising quarter. After taking in more than $200,000 in the second quarter, the former Independent Party lieutenant governor candidate has over $300,000 cash on hand.
