Paul claims the just war idea comes from Christianity which isn't true. It comes from Judaism and the Torah will note that.
What do You think about limiting campaign funds strictly to citizen donations not to exceed One Thousand Dollars. No SElf Funding or any other type. No Super Pacs, along with NO TV Ads, just Debates?
Why did Rick Santorum's wife file a medial malpractice lawsuit against her doctor for $500,000.00 when Rick preaches that medical malpractice lawsuits should and would be limited to $250,000.00 under his administration. Why is Rick's wife immune from what Rick preaches.
I thought Romney could pull it off–nope 1%. Then I thought Santorum–nope to weak. Gingrich doesn't stand a chance–too dodgy. None of them can beat Obama. The GOP needs to wake up and smell the coffee.
I currently work 2 part time jobs and my wife does as well, together we barely make ends meet. What would you do to help the struggling lower class at home?
I am from Somalia, I wanna know if you are elected how can you help without military support Somalian Government to eliminate the threat we Face In Somalia, Middle East and United States of America? I never heard any candidatetalking about Africa.
Sopa? Pipa? Partriot Act? Proctection of civil liberties, privacy, censorship? Patent and intellectual property protection?
For all the candidates: You all say Obama Care is a bad idea but what are your ideas on making health care affordable for all Americans. Especially Arizonans since we are not able to buy health care from companies outside of Arizona
Really sucks that we can't even hear a third of this on CNN. It keeps cutting out so who was in charge of this one???? What a waste at least in Ohio. This stinks guys. Thought you had better tech than this. Cannot believe you allowed this to go on tonite. Even you dumb commercials we can't hear.
My question is for all candidates" What will you do to fix inflation of the weakening U.S. dollar?"
John King, please (without personally attacking any of the candidates) hold the candidates to actually answering the questions! Not one of them answered the contraceptive question!
Please!!! Stop debating President Obama when he's not there to debate you! Debate each other to see how you 4 differ. I look at you 4 and see a cakewalk for President Obama. Ron Paul is the only one who makes sense, is genuine and has a clue. Unfortunately, the country and the world would not accept him as being "Presidential".
Why are we giving illegals school, medical amminities, for free, when our own children struggle to pay for this themselves?
Why does our gov't. pay for this???
To: Mit Romney, there are 906 pages in the Patient Protection Affordable Care Act. Also, to Mr. Santorum: You acknowledged that you shouldn't have voted for 'no child left behind'. Fair enough. But then you say that in order to cut spending, essentially we are dumping public school systems entirely and leaving it up to the local systems and community to support and fund. Could you please explain to me how lower-class community's are going to be able to afford an Increase in their Local Taxes? Thank you
The ex-head of the CIA's Bin Laden unit, Michael Scheuer, recently appeared on several news stations. He is in agreement with Dr. Paul's assessment of the middle east conflict and how to resolve it. When a superior voice who has spent years on the front line be listened to, and how can we justify our continuation of a clearly failed policy?
I am considering voting Republican for the first time in my life. To each of the four–How do you convince me to follow through?
What's with this tacky and apparently stacked audience and their "booing"? This is getting extremely distracting from the candidates responses.
Mexico is a threat, really Mittens, you're reaching boo. What's the threat some American falling off a bar stool at Senior Frogs? President Obama dangerous all right if you're a Somali pirate, or a member of al quaeda. Face it Repububs you can lay claim to "keeping us safe" anymore, bascially you got nothing but look at me I'm not Obama.
Rick always stumble when he has to answer a criticism of his policy or ideas.
Ron Paul is correct – these birth control pills are not the government's business.
We have bigger issues to deal with than contraception.
Good grief – why, oh why can't the GOP get it's act together and promote Ron Paul?
I live in deep south Texas about 2 miles from the border on clear nights I can hear the gunfire. How will you stop spill over violence and how will you stop Mexico from becoming a full Narco-State. Please be very specific.
John King asks too many softball questions. In SC he asked the weak question to Gingrich. Tonight he asks who believes in birth control. The real question should have been about the candidates' position on the 10th amendment and whether a state could outlaw birth control as we used to have. This is what Santorum had suggested. Also since all 4 say they will repeal Health Care Reform, what about the 3 who seved in Congress and used taxpayer funded Congressional health care? Would the candidates push to repeal Congressional health care?
Many Republican voters that I know have cut their support from some of the current Republican candidates because they support HR 1540. Do you (all of the candidates please answer) support HR 1540 and why?
My question is when will the jobs come back to this country? How can a government health care plan take effect if people do NOT have jobs to pay the taxes that will pay for the Health care. Has any of you (Rep.Candidates ) thought of a Equal Work Act? For every person a company has employed in the States; that is the limit of how many they can have over seas.
In recent history, all modern, traditional wars involving the United States have been fought on foreign land. How would you respond to a traditional war waged and fought on United States soil?
