If you apply for any job and your potential employer asks you if you agree with their company's policies and product, and you say, no, you won't get hired.
It's about loyalty.
If I was interviewing people that wanted to represent the Republican Political Party, I would strap them to a polygraph machine and ask them some of the following questions:
1. Are you a Marxist or Socialist? If they answer yes, toss them out the door.
2. Do you support the Constitution and its Bill of Rights, as is? If they answer no, toss them out the door.
3. Do you believe in having national borders with strong border control and merit based entry? If they answer no, toss them out the door.
4. Are you a strong supporter of the Republican Party? If they say yes, but the Polygraph indicated deceit, toss them out. (You want to eliminate the RINO's)
