PROVIDENCE, R.I.—General Treasurer Frank Caprio, who is also the Democratic candidate for governor, is asking a federal judge to uphold Rhode Island's system of public financing for political parties.
Under the current system, state taxpayers can voluntarily contribute small sums to political parties by checking a box on their tax returns.
The Moderate Party, a new political party in the state, has sued. It says the system is unfair and set up to benefit Democrats and Republicans while hurting third parties.
But Caprio says in court papers that the formula is fair and has not put the Moderate Party at any real disadvantage.
Arguments in the lawsuit are scheduled Thursday morning before U.S. District Judge William Smith.
