There are going to be a lot of disappointed people no matter who wins the presidency Tuesday.

Mitt Romney and Barack Obama both have roughly the same number of supporters heading into the polls, and it's looking like whoever wins is going to just barely eke out that victory.

It doesn't matter which candidate you back -- your man needs your vote in an election this close.

But if you don't exercise your most fundamental right, you also lose your right to complain -- no matter how disappointed you might be.

You had your chance. And it might have made a difference, especially this year.

In the 2008 presidential election, 69 percent of York County's registered voters went to the polls. That's great compared to the measly numbers posted in non-presidential elections -- just 14 percent of register voters showed up for last November's election.

But that means 31 percent didn't bother to help select our president. Not 31 percent of the county population -- 31 percent of people who took the time to register and were eligible to vote. (And to think a certain party wants to make it harder for Pennsylvanians to vote ...)

If choosing the person who will lead our country and set the national agenda for the next four years isn't important enough make an effort ... well, like we said, don't complain about who you get.

This presidential election is particularly important, given the monumental tasks ahead and the candidates' very different views on how to deal with them.

Whoever wins the White House will have to work with Congress to move any agenda forward, and that particular body has become a dysfunctional mess, unable to accomplish even the simplest work.

But you have a chance to make a difference there, too.

For the first time in 12 years we'll elect a new representative to the 4th Congressional District. Democrat Harry Perkinson and Republican Scott Perry are vying to replacing retiring Rep. Todd Platts.

And Republican Tom Smith is challenging incumbent Democrat Bob Casey to represent Pennsylvania in the Senate.

Again, in both cases, very different views and very different approaches.

Those are the big-ticket, high-profile races, but also on the ballot will be a number of state House and Senate contests.

The winners in these races will be making decisions that affect you closer to home -- how much money goes to your child's school, whether your roads are repaired and what kinds of social services are available.

So vote Tuesday and make a difference.

Or at least earn your right to gripe.
