I believe the answer is:
1.conservative stance on most social issues
For example, the issue regarding abortion. Republicans see that life begin as soon as a fetus is conceived, which is why they provide no room for giving rights to do an abortion.
3.highly popular successful presidential candidate Ronald Reagan
Ronald Reagan was known for creating a competitive environment for business to thrive and promote economic growth.
5.famous first president, Abraham Lincoln
His fame came specifically from his stance against slavery.
