Food stamp use is on the rise. If you are president, will you consider restricting EBT purchases as they do with WIC purchases?
Senator Santorum, during your 1990 campaign againts Rep. Doug Walgreen as reported in the Pittsburgh Post Gazette on 10/28/1990 you said that you limited your opposition to abortion to cover only the time the fetus is considerd viable-usually taken to mean the final 3 months of pregnacy, Why you have changed?
Question for all candidates; As president of the United States, would you re-instate the policies of Dont Ask Dont Tell?
Who supports the NDAA Bill and why?
Senator Rick Santorum asserts he is the most conservative candidate in the election. However, considering his low rating with moderates and independents, what makes Mr. Santorum think he will beat President Obama in the General Election?
Anyone on the panel can answer this question: How does same sex marriage effect you and your family?
I would like Mitt Romney clarify his comments regarding Federal Employees. He stated that Federal employees should not make more than their private sector counterparts, and Federal employees should not make more than tax payers.
Does he not realized that Federal employees pay taxes too? Essentially Federal employees are paying for part of their own salaries. How many private sector employees pay part of their own salary with their own tax dollars?
Also, he does not mention Federal employees that make significantly less than their private sector counterparts. What are his plans to address that?
How do we teach and grow our future leaders when college costs continue to skyrocket?
To all GOP candidates, when are you going to focus on the failures of the current administration instead of playing the tit for tat games on the debate stage? When are you going to talk about foreign policy like the failure of the current administration to deal with the mass murders in Syria? What are you going to do about our critical relationship with Israel? What are you going to do to ensure that we aren't stuck paying over $3.50 per gallon forever? What will you do to ensure that the economic environment invites business growth and productivity and ensures that our doctors have the freedoms to run their small businesses while making the profits they deserve? You all need to focus on the important policies of today and tomorrow, instead of the little things that won't help you get elected.
what are they going to do for education?
Romney is looking at Santorum like he wants to vote.for Rick instead of himself....lol
Question for Ron Paul: You never got to actually mention how you would cut spending, I'd like to hear what you have to say towards the first question which pertained to how you would cut the $14 trillion dollars.
I am a firefighter who is also involved in the International Association of Firefighters . The IAFF has been known to put more GOP candidates into office. What will you do to help insure the survival of benefits for our public services in our country?
Why do Republicans not want American woman to enjoy reproductive freedom?
why is Romney always given the time to talk? what about Ron Paul? Gingrich?
I love it how CNN and all of the main-stream media give the front runners most of the time? Ron Paul always gets ignored clearly the most, because they are scared of what he has to say!
To all candidates: If you were currently president of the US, how would you handle the growing possibility of a nuclear Iran and the threats of war being exchanged between Israel and Iran?
Newt. The boarder is not the problem. It will be free of charge to change the 14th Amendment to the Constitution. China will be invading us within a few years because they are outsmarting us while we sleep. They are visiting America for the sole purpose of having natural born babies and then they are returning to their country to raise them. As the child becomes of age, the intention is American college education followed by jobs. They are natural born citizens. It is my understanding that thousands of babies are born each month.
(To Any of the candidates, but especially Rick Santorum) Many Republican constituents (and candidates) espouse that The United States was founded upon Christian values. How do you reconcile that contention with the Treaty of Tripoli, ratified unanimously by Congress in 1796, which states, "the Government of the United States of America is not, in any sense, founded on the Christian religion"?
Give Me Your Money
If elected president I will steal everybody's money and tie the people up in foreign entanglements. Then I will cause false flags at home and wag the dog at every opportunity. When I am in my final year I will invent a bunch of phony programs to get one last tax to pay for my exit to the Bahamas where I will live it up with my crooked family and friends and laugh together about what a bunch of stupid rubes Americans are.
I want John King to ask former Senator Santorum why is has been attacking President Obama's faith and attacking women's rights.
What are the candidates opinions on the current battle over teacher evaluations? What are their respective plans to fix the education system without demonizing those who have chosen a career in education?
As President would you be in favor of complete elimination of earmarks? And would you be in favor of passing a bill by simple majority just like in the British Parliament?
To all Candidates:
Do Fannie Mae and Freddie Mac were created to help working class Americans buy homes, an integral part of the American Dream. Do either Fannie or Freddie have a future in the US Economy?
Candidates often invoke the Reagan legacy. What aspects of other Republican presidents' legacies are you prepared to promote, in particular the most recent, George W. Bush?
