Why is the presidential line of succession by position title rather than name?

To avoid problem that may arise due to the change in position of those holding a particular post at a time, as it is easier and better to use postion title rather the name of people holding the position in the Presidential line of succession

Explanation:

The present presidential line of succession, was created under the Presidential Succession Act of 1947, signed by President Harry Truman.

It specified the order, in which the cabinet members are ordered in the line of succession according to the date their offices were established.

The current presidential line of succession is as follows:

1. The Vice President

2. Speaker of the House

3. President pro tempore of the Senate

4. Secretary of State

5. Secretary of the Treasury

6. Secretary of Defense

7. Attorney General

8. Secretary of the Interior

9. Secretary of Agriculture

10. Secretary of Commerce

12. Secretary of Labor

13. Secretary of Health and Human Services

14. Secretary of Housing and Urban Development

15. Secretary of Transportation

16. Secretary of Energy

17. Secretary of Education

18. Secretary of Veterans Affairs

19. Secretary of Homeland Security

Hence, in between this position, a holder of such position might have changed his or her position when the presidential seat is vacant and need to be filled only by the next in line of succession rather than election.

Therefore, to avoid problem that may arise due to the change in position of those holding a particular post at a time, it is easier and better to use postion title rather the name of people holding the position in the Presidential line of succession
