Editor's note: We're listening to you. Every day, we spot thought-provoking comments from readers. Here's some comments we noticed today.
The Civil War we read about in U.S. history books took place in the 1860s, but even today people are talking about the possibility of it happening again. A Lubbock County, Texas, judge named Tom Head stirred up controversy when he said the United States would enter such a civil war if Obama were re-elected. Texas Democrats are calling for his resignation. The story got more than 17,000 comments about political boundaries, and about what it means to disagree and fight.
Does it matter who is president? (Putting aside views about what constitutes a "good president" for a moment.)
Picturamadoj: "If we didn't have a Civil War when Bush was in office, why would anyone think we'd have a Civil War with a good president like Obama?"
bhartman36: "We had a civil war when Abraham Lincoln was in office, too. The quality of the president has nothing to do with whether or not there's civil war."
Some readers griped about Republicans.
kkhjlh: "Talk about extreme politics. Does the Republican party really endorse this garbage? And they want to run the country."
But some blamed the president.
Jakerman: "Proof of how Obama has divided the country? Read the posts on here."
And a few others said maybe secession isn't such a bad idea.
RubinL: "So secede already! This time, not only won't we try to stop you, we'll even help you pack."
