On May 2, Kathleen Curry, an independent write-in candidate for the Colorado legislature in 2010, filed her opening brief in the 10th circuit in Riddle v Hickenlooper, 13-1108. This is the lawsuit that challenges Colorado law that lets individuals contribute $400 to a candidate for the legislature who is nominated by primary, but only $200 to a candidate for the legislature who is either a write-in candidate, or a petitioning candidate, or a candidate nominated by convention.
