The California Republican Party drew a line in the sand this afternoon by voting at the end of its three-day convention to oppose “any tax extension, new taxes or tax increases by the Legislature” even if such measures are tied to spending caps or other reforms. That stance contrasted with statements made by some officials at the convention that Gov. Jerry Brown needed to seriously consider reforms if Republican legislators would weigh putting some $11 billion in tax extensions on the ballot, as Brown is asking. New state GOP Chairman Tom Del Becarro told reporters that the tax stance would change the debate in Sacramento. He also questioned whether Brown was serious about pension reforms, spending caps and other changes.
