Each step on the campaign trail is bringing candidates closer to the White House, and on Super Duper Tuesday voters in more than 20 states will go to the polls.

Presidential candidates are working to win over as many undecided voters as they can before the big day. However, the shape of the primary calendar suggests that the presidential nominating race could be over before Pennsylvanians get the chance to vote.

Political pundits and experts around DC are naming Tsunami Tuesday as a truly historic moment in the history of American politics.

But Pennsylvanians are left out of the excitement because the state decided not to change its traditional spring primary date. It will be the last of the nation’s most populous states to hold its primary.

If PA had moved the primary up, it would be a big player in the early primary races. But don’t discount the Keystone State’s significance. Each party’s candidate will hopefully be trekking through Pennsylvania to win the states electoral votes later this year.

In the past week alone, hot candidates dropped out of the race and endorsements have been flying out of the hands of some of the nation’s most prominent lawmakers.

A few weeks ago our local Congressman Phil English backed his favorite candidate. He told me outside his Washington office that he was supporting Rudy Giuliani. Since then, Giuliani dropped out. It just goes to show you how quickly everything is happening. I’m sure English wouldn’t have backed a candidate he expected to lose.

Perhaps to avoid that situation Congressman John Peterson and Pennsylvania Senators Arlen Specter and Bob Casey have not made any endorsements yet. (Despite my constant calls as well as the nagging of other regional reporters in Washington.)

This past Monday, Specter told me that he will endorse a candidate, but he’s waiting until the time is just right. Pennsylvania lawmakers could be waiting for the results of Super Duper Tuesday before they make their pick.

It’s tough to say what the impact of the big day is going to be. Sure, two candidates could come out as definite frontrunners. But let’s not forget that there are votes (like Pennsylvania’s) to be won after Tuesday.

Many of us that are watching these nominating contests so closely are hoping that Super Duper Tuesday can still lead to suspense filled brokered conventions later this year. But at this point, I'm not positive we should bet on it.
