Obama most likely Democrat to unify America - The State editorial board's Democratic presidential primary endorsement

This accurately expresses why Barack Obama...

On positions from Iraq to health care, the policy differences between Sen. Hillary Clinton and Sen. Barack Obama are minute. Much of the debate between them has involved making these molehills look mountainous or clashing over who-shifted-when.

The one most significant difference between them can be found in how they would approach the presidency - and how the nation might respond.

Hillary Clinton has been a policy wonk most of her life, a trait she has carried into the U.S. Senate. As her debate performances have shown, she has intelligence and a deep understanding of many issues. Her efforts in New York focused first on learning her adopted state’s issues in detail, and pursuing legislation that would not necessarily grab headlines.

But we also have a good idea what a Clinton presidency would look like. The restoration of the Clintons to the White House would trigger a new wave of all-out political warfare. That is not all Bill and Hillary’s fault - but it exists, whomever you blame, and cannot be ignored. Hillary Clinton doesn’t pretend that it won’t happen; she simply vows to persevere, in the hope that her side can win. Indeed, the Clintons’ joint career in public life seems oriented toward securing victory and personal vindication.

Sen. Obama’s campaign is an argument for a more unifying style of leadership. In a time of great partisanship, he is careful to talk about winning over independents and even Republicans. He is harsh on the failures of the current administration - and most of that critique well-deserved. But he doesn’t use his considerable rhetorical gifts to demonize Republicans. He’s not neglecting his core values; he defends his progressive vision with vigorous integrity. But for him, American unity - transcending party - is a core value in itself.
