I know you read opinions about the 2008 presidential campaign in this paper (and, I’m sure, many others) several times a week. With the race dragging on, and a Democratic nominee becoming slightly clearer, you’re probably sick of hearing about it.

But after traveling throughout Indiana last week to write about the state’s primary for a political blogging class, I came to a conclusion that needs to be shared.

Barack Obama must be president for this country to truly change.

Despite the candidate’s overwhelming influence on the college-age demographic, I was never fully on the Obama train. I leaned toward his critics’ arguments about his lack of experience and their apprehensions about the world’s readiness for a black president.

But after hearing speeches from and attending rallies for both candidates, my voting sentiments have become clear. Obama will deliver the change that many candidates say they will bring because of his ability to inspire and, most importantly, to mobilize.

The day before Indiana’s primary, I attended an Obama rally in Indianapolis that drew a crowd of 20,000. In addition to that number inside the park where it was held, perhaps a thousand more gathered on sidewalks, doorsteps and anywhere else that was within earshot of the event.

During his speech, Obama talked about the presidential campaign being about the American people. He called for a acceptance and unity that transcends the boundaries of ethnicity, sexual orientation and religion. Consequently, the candidate created an enthusiasm that was evident not only during the event, but that stayed with the crowd as they left the park.

It’s creating a sentiment like this — one that can be maintained — that gets people moving. And it’s mobilization, particularly in this capacity, that brings change.

Legislation can be passed and executive decisions can be made, but only citizens actively engaging in these politics can truly make a difference in society. It’s up to the American people to integrate not only laws, but also the philosophies behind them into everyday life for them to be valid.

As much as I respect Hillary Clinton’s ambition and goals, she just doesn’t cut it. Her Indiana rallies drew hundreds, a few thousand at most. The Clinton supporters I met liked her because she’s a good role model for young women and because she promises to help the economy. None mentioned her ability to mobilize the American people, probably because it’s not as strong as Obama’s.

McCain promises to mobilize as well — troops, that is.

What our country needs is a passion to put politics into practice. Rather than leaving it up to the White House, and letting things be said — not done — citizens must stake a claim in how the United States is run by being actively involved.

And with an all-inclusive dream, Obama is our only hope.
