Answer:
No, Brian Russell is not old enough if he runs now.
However, he can still run provided that he turns 35 years old upon filing for the position.
Step-by-step explanation:
The Qualifications for office (for serving as President of the United States) states that the person must be a natural born citizen, at LEAST 35 years old and an inhabitant of the United States for at least fourteen years. These are the qualifications needed in order to run for the position.
It is clear that the 34-year-old Brian Russell is NOT eligible to run for the position owing to his age. However, if he turns 35 years old before filing to run for the position, then he can be old enough to run. Election normally happens on the month of November of the year. This means he still has time to file for the position.
