Voters will set the course for Arizona as they cast their ballots today on Proposition 100, the 1-cent-per-dollar sales tax that would boost revenue for public education, public safety and public health care.

Prop. 100 should pass. It won't fix all of Arizona's problems, but without the revenue generated from the three-year sales tax increase, our state will surely suffer damage. Without that patch, essential services will be cut back to a degree that will cause lasting harm.

More than 110,000 ballots have been cast early, which is about one-quarter of the registered voters in Pima County, according to the Pima County Elections Department.

A couple of tips to make your trip to the polls smoother today:

Check where your polling place is located - it's not necessarily where you voted in the last election, as officials change the locations based on anticipated turnout and availability of facilities. Check at the Pima County Recorder's Office at voter_info.aspx

The complete language for Prop. 100 can be found at the Pima County elections site at canpage.htm

Polls are open from 6 a.m. to 7 p.m. - if you're in line at when the polls close, you may still cast your ballot.

If you have an early ballot that you haven't yet mailed, bring it to a physical polling place and drop it off. It is too late to mail - it must be in hand at the Elections Department by the time polls close at 7 p.m.

Remember that you must provide proof of identification to vote today. This has been the law in Arizona for several years, but it seems to come as a surprise to folks who aren't regular voters.

Voters may present one of the following photo identifications: a valid Arizona driver's license or non-operating identification, a tribal enrollment card or other form of tribal identification, or a valid U.S. federal, state or local government-issued identification. The address on the identification must match the address listed on your voter registration.

Without photos, you can show two forms of identification showing a name and address, including utility bills or bank statements dated within 90 days of the election, a property-tax statement and a valid Arizona vehicle registration.

For more information on identification or poll locations, call the Pima County Recorder's Office at 740-4330.

We think that Prop. 100 is necessary for the future of Arizona and encourage you to vote for it. But no matter how you vote, the most important thing is that you cast your ballot today. This election is crucial for the future of Arizona.
