McCain was far more qualified than Bush was. 20 years in the Navy and 30 years in Congress... How do you get more qualified than that?
How does 20 years in the U.S. Navy qualify one for President of the United States? Mopping decks or manning guns doesn’t even remotely qualify one to be president.
And as far as being in Congress - that’s the legislative branch, snowflake. The President of the United States exists in the executive branch. They aren’t even the same branches of government, you dimwit. So that definitely doesn’t qualify one to be president.
