According to campaign finance reports, Republican lawmakers who supported Gov. Brian Sandoval’s tax package have outraised their anti-tax Republican challengers so far this year. Those incumbents now face a test at the ballot box, where voters will choose between different stripes of Republicans in the June 14 primary and during the early voting period that started Saturday.  The reports, released last week show that more moderate Republican Assembly members backed by Majority Leader Paul Anderson have individually raised more money than candidates backed by anti-tax incumbent Republican Assemblyman Brent Jones.
