A federal judge says he'll likely rule in favor of a lawsuit challenging Hawaii's open primary election if he finds there's a "severe burden" on the First Amendment right to free association.  Judge J. Michael Seabright said at a hearing yesterday that the case could ultimately end up before the U.S. Supreme Court. The Democratic Party of Hawaii filed the lawsuit claiming the primary system allowing every registered voter to participate in the party's nomination process is tantamount to forced political association and is unconstitutional.
