As the end of the Oregon Legislative session nears, the fate of a diverse set of tax credits may be the biggest issue that remains to be resolved.  House and Senate Democrats are struggling to reconcile proposals blending the tax credits, which without a deal would expire on January 1 of next year, with some revenue increases that would target corporations.  Republican 29th District Senator Bill Hansell says his party isn’t happy with plans to consider the credits and increases in one package, rather than separately.  Republican legislators argue the package is an attempt to skirt the three-fifths supermajority requirement for passage of revenue bills.
