Editor's note: We're listening to you. Every day, we spot thought-provoking comments from readers. Here's some comments we noticed today.
As the Republican National Convention moves forward, politically charged comments flow like water. Readers called for a few tidbits of unity on the story about Arlen Specter's fight against cancer. Specter, 82, was the longest-serving senator from Pennsylvania and switched from being a longtime GOP member to the Democratic Party in 2009.
Readers mused about Specter's political history in the current divided climate. Several commenters thanked Specter.
Hottampa: "Thank you Arlen Spector for the service for your country. I hope you recover. If you do not, you lived a long productive life that most people envy."
iBod: "It's odd, because I was just thinking about him yesterday - wondering how he is spending his time away from the Senate; how he is doing, overall. Dearly saddened to hear this. I am sure this news is hitting all of us Pennsylvanians pretty hard. My thoughts and prayers go out to him and that he makes a full recovery."
PeteArk: "He is a man of moderate views and a love of country ... unlike many of those now in the political arena ..."
Push politics aside for a moment, this reader pleaded.
VelveteenLdy: "It is, at once, amazing and disgusting that almost everything in the news today can be turned into a political battlefield. The purpose of these posts is not to argue Sen. Specter's politics, but to comment on the article. The man is dying. His political affiliation, actions, or whether he was liked or disliked are immaterial and inconsequential to that fact. My thoughts and prayers go to Sen. Specter's family and I pray that he passes on in comfort and in peace."
Many of the readers claimed to be Pennsylvanians, and gave a local perspective.
Dave: "As a Pennsylvanian, I am no Specter fan and voted against him. I donated money to his opponent Sestak. With that said, I hope he does not suffer. Cancer is a horrible disease. That is why we need more funding for cancer research - and why we need Democrats in Washington, because the GOP wants to cut cancer research to pay for millionaire tax cuts."
Tebojockey: "Fellow Pennsylvanian here. I agree with you. I hope he does not suffer. Arlen was always entertaining, however. God forbid he should go, but if he does, he will learn the error of his way on his 'one bullet theory' when he gets wherever it is he's going to. I grew up with this guy in my life most every day. It will be strange not seeing his name or image around if he goes ..."
The above commenter is referring to Specter's service on the Warren Commission, which investigated the death of Sen. John F. Kennedy. Specter is credited with co-authoring the "single bullet theory" suggesting that one bullet caused some of the wounds to Kennedy and then-Texas Gov. John Connally.
Some posters got into a fascinating debate about the degree to which one can compromise on their beliefs.
2743: "I don't like label so I am not sure that I am a liberal but I am disgusted when people make remarks about peoples health including Dick Cheney who I agree with nothing on. The lack of rational discourse the name calling and extreme partianship is gettiung us nowhere. Political differences should not make us hate each other. We need to compromise."
thunderbolt0: "Why I agree with part of your post, you lost me with compromise. I don't want compromise unless it makes a policy or situation better. We got into the banking bubble, and the housing bubble all because of making the wrong compromises. I would have agreed with you better if you had left that part out and replaced it with what best helps our people.
einna: "What you are saying is exactly what the problem is right now. Not every side is going to agree on what is best, so sometimes the sides need to reach a compromise that helps the majority. Neither side may say this is making it 'better,' but what is considered 'better' may be what is in disagreement. There are times that it is best to have something halfway, if no one can agree on what the 'whole' should look like. Think of a peace treaty - is it better to stay at war forever, or allow both sides to give up some stuff in order to stop the killing?"
