On January 26, Oregonians will be asked to decide how the latest chapter in the state's long-running tax wars will turn out. Opponents of two tax increases approved by the legislature in 2009 succeeded in collecting enough signatures for a referendum on what are now Measures 66 and 67. The former would raise the state income tax rate on those earning more than $125,000 per year while the latter would increase the minimum corporate tax. Supporters of the measures say vital public services are at stake. Opponents say raising taxes during a recession will only make matters worse.
