MADISON, Wis. (AP) – Candidates for the Wisconsin Supreme Court and state superintendent are reporting little fundraising activity so far heading into the April 2 election.  Three candidates vying for the Supreme Court while two running to lead the state Department of Public Instruction are required to file reports Thursday showing how much they had raised and spent through the end of last year.  Incumbent Supreme Court Justice Pat Roggensack reports raising nearly $39,000 last year and having a little over $55,000 cash on hand. One of her challengers, Milwaukee attorney Vince Megna, reports raising about $10,700 and having nearly $7,000 on hand.  Superintendent candidate, Republican state Rep. Don Pridemore, reports raising nearly $62,000 but most of what he raised came from a $49,000 loan Pridemore made to his own campaign.
