The historically Republican newspaper has crossed sides for the first time in its history to endorse its native son:

The Republican Party, the party of limited government, has lost its way. The government ran a $237 billion surplus in 2000, the year before Bush took office -- and recorded a $455 billion deficit in 2008. The Republicans lost control of the U.S. House and Senate in 2006 because, as we said at the time, they gave the nation rampant spending and Capitol Hill corruption. They abandoned their principles. They paid the price.

...

We do, though, think Obama would govern as much more of a pragmatic centrist than many people expect.

We know first-hand that Obama seeks out and listens carefully and respectfully to people who disagree with him. He builds consensus. He was most effective in the Illinois legislature when he worked with Republicans on welfare, ethics and criminal justice reform.

...

When Obama said at the 2004 Democratic Convention that we weren't a nation of red states and blue states, he spoke of union the way Abraham Lincoln did.

It may have seemed audacious for Obama to start his campaign in Springfield, invoking Lincoln. We think, given the opportunity to hold this nation's most powerful office, he will prove it wasn't so audacious after all. We are proud to add Barack Obama's name to Lincoln's in the list of people the Tribune has endorsed for president of the United States.
