Answer:
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
Step-by-step 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
