That upon the receipt of a veto message from the governor each house of the legislature shall enter the same at large upon its journal and proceed to reconsider such bill, or part of a bill, and again vote upon it by ayes and noes, which shall be entered upon its journal.

If after such reconsideration such bill, or part of a bill, shall be approved by a two-thirds vote of all the members to which each house is entitled, it shall thereby become law.
