"Yet if Obama does become the nation's 44th president, his election will constitute something approaching a definitive judgment of the Iraq War. As such, his ascent to the presidency will implicitly call into question the habits and expectations that propelled the United States into that war in the first place. Matters hitherto consigned to the political margin will become subject to close examination. Here, rather than in Obama's age or race, lies the possibility of his being a truly transformative presidency." Original Link Bruce Bartlett, writing in the New Republic, cited Obama's opposition to the Iraq War as the main issue which appealed to conservatives.

"Back in the 18th century, Helvetius said, "When I speak I put on a mask. When I act, I am forced to take it off." Too many voters still have not learned that lesson.

People need to start asking that question about Obama."

This wave of endorsements led The Economist to publish an in-depth examination of "The Rise of the Obamacons" and their influence:

The biggest brigade in the Obamacon army consists of libertarians, furious with Mr Bush's big-government conservatism, worried about his commitment to an open-ended "war on terror", and disgusted by his cavalier way with civil rights. ... For many conservatives, Mr Obama embodies qualities that their party has abandoned: pragmatism, competence and respect for the head rather than the heart. Mr Obama's calm and collected response to the turmoil on Wall Street contrasted sharply with Mr. McCain's grandstanding. ... How much do these Obamacons matter? More than Mr McCain would like to think. The Obamacons are manifestations of a deeper turmoil in the Republican rank-and-file, as the old coalition of small-government activists, social conservatives and business Republicans falls apart. They also influence opinion. ... The more tantalising question is whether the rise of the Obamacons signals a lasting political realignment. ... If the Republican Party continues to think that the problem lies with the rats, rather than the seaworthiness of the ship, then the Obamacons are here to stay.

The rush of Republicans and other conservatives openly endorsing Barack Obama was the subject of satire on the television show The Colbert Report on October 29, 2008, which drew record ratings with a self-serving endorsement by the conservative host character played by comedian Stephen Colbert.

The Wall Street Journal characterized the Obamacans as "the latest sign that the Republican Party's coalition is fracturing."

Polling data The final election Gallup Poll, from October 27 to November 2, indicated 10% of Republicans supported Obama instead of McCain, compared to 7% of Democrats who supported McCain. Gallup also indicated his support among self-described conservatives, although stronger than John Kerry's, was weaker than what Al Gore received. In August, Andrew Romano of Newsweek stated that the polls he had read indicate the cross-over voters "cancel each other out." However The Economist cited a poll in late October 2008 that indicated Obama was "winning 22% of self-described conservatives, a higher proportion than any Democratic nominee since 1980."
