The Arizona Senate has given preliminary approval of a bill that would limit state government spending.
The bill would only allow limits to be modified based only for population growth and inflation.
Supporters say the bill would help prevent the state from overspending.
Opponents say tightened spending limits are not realistic formulas and will hurt small business, families and senior citizens.
The bill is roughly modeled on a Colorado constitutional amendment known as the Taxpayer Bill of Rights.
The bill now awaits a full Senate vote. Passage would return it to the House.
