Measure 41 would have restricted the amount of money the State government could raise through income tax, by allowing taxpayers to claim a credit for Federal income taxes. It was similar to Ballot Measure 88, rejected in the general election of 2000. Measure 41 was rejected, winning 37.1% of the vote (483,443 votes out of 1,301,895.)
Measure 48 (a version of the Taxpayer Bill of Rights) would have restricted the amount of money the State could spend in its annual budget. It was rejected, winning 29.1% of the vote (379,971 votes out of 1,303,600.)
TAO received 94% of its funding from Illinois-based Americans for Limited Government, which sponsored similar measures in numerous states in 2006. Opposing groups also pooled their resources in pushing for the defeat of both measures, spending $1.9 million.
