Capsule descriptions of the eight measures appearing on ballots statewide in Arizona's Nov. 4 general election:

PROPOSITION 100: This initiative would amend the Arizona Constitution to prohibit the state or local governments from enacting a new tax or fee on real estate sales. Supporters say a real estate transfer tax would weaken the economy, hurt home affordability by hiking home prices and constitute double taxation because of existing property taxes. Opponents say there already are restrictions on imposing new taxes and that the state must keep open its options because of its current budget troubles. Supporters include groups representing home builders and real estate agents. Opponents include the Arizona Education Association.

PROPOSITION 101: This initiative would amend the Constitution to prohibit laws that restrict a person's freedom to choose private health care plans or to decline coverage in any particular health care system or plan. Supporters say some proposals to expand health care coverage could restrict consumers' right to pick care systems and providers. Opponents say it would restrict the state's options for increasing health care availability. Supporters include current and past leaders of groups representing physicians, chiropractors and dentists. Opponents include Healthy Arizona and the Arizona Chamber of Commerce and Industry.

PROPOSITION 102: This initiative would amend the Constitution to define marriage as only a union between one man and one woman. Supporters say a constitutional provision would protect the sanctity of marriage by preventing judges from overturning the existing state law prohibiting same-sex marriages. Opponents say the amendment is not needed because an appellate court has upheld the existing prohibition on same-sex marriages. Supporters include the Center for Arizona Policy and United Families International. Opponents include the League of Women Voters of Arizona and the Arizona Advocacy Network.

PROPOSITION 105: A proposed constitutional amendment, this initiative would raise the voter-approval threshold needed to pass initiatives that raise taxes or require new spending. Specifically, it would require that such measures be approved by a majority of all registered voters, not just those voters casting ballots. Supporters say it is needed to restrain advocacy groups' demands for increased spending or taxes. Opponents contend it would make it virtually impossible to win approval of most initiatives. Supporters include the Arizona Tax Research Association and the Arizona Farm Bureau. Opponents include the Arizona Education Association and the Arizona School Boards Association.

PROPOSITION 200: This initiative would indefinitely extend the authorization in state law for payday loans - "deferred presentments" - past the current July 1, 2010, expiration. It also would make such changes as prohibiting a lender from making a new loan to a customer who already has a loan outstanding and requires allowing repayment plans on request before a transaction is due. Supporters say the loans serve customers who otherwise couldn't get credit. Opponents say payday loans can lead to perpetual debt traps for inexperienced borrowers. Supporters include state Rep. Steve Gallardo, D-Phoenix, and a group representing payday loan lenders. Opponents include Arizona AARP and Attorney General Terry Goddard.

PROPOSITION 201: This initiative proposal would change state law to expand warranty rights for property buyers. Requirements include a 10-year warranty on new homes and use of licensed contractor to make warranty repairs. Supporters say it would help protect customers from bad-actor homebuilders. Opponents say the initiative opens the door to frivolous lawsuits and is a union pressure-tactic against homebuilders. Supporters include the Sheet Metal Workers union and the Arizona Advocacy Network. Opponents include home builders groups and the Arizona Chamber of Commerce and Industry.

PROPOSITION 202: This legislative proposal would make business-friendly changes to Arizona's employer sanctions law, which prohibits businesses from knowingly hiring illegal immigrants. It would tighten rules for making employer sanctions complaints and strengthen a protection for employers who follow the rules. Supporters say the measure is meant to target dishonest employers and protect honest ones. Opponents say the proposed changes would make it difficult for authorities to bring cases against violators. Supporters include restaurant operators and agricultural interests. Opponents include Maricopa County Attorney Andrew Thomas and the sanctions law's author, state Rep. Russell Pearce.

PROPOSITION 300: Placed on the ballot by a state commission, it would raise annual salaries of the 90 state legislators from the current $24,000 to $30,000. Besides their annual salaries, lawmakers also get a daily stipend when the Legislature is in session. Supporters say lawmakers are underpaid and that raising their pay would enable a broader range of Arizonans to serve in the Legislature without depending on outside sources to supplement their incomes. Opponents say it's not a good time to give lawmakers a pay raise. Supporters include members of the state Commission on Salaries for Elective State Officers. Opponents include Gov. Janet Napolitano.
