The Constitution of the United States: Article I, The Legislative Branch
Section 4 - Elections, Meetings
The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Place of Chusing [choosing] Senators.
The Congress shall assemble at least once in every Year, and such Meeting shall (be on the first Monday in December,) (The preceding words in parentheses were superseded by the 20th Amendment, section 2: “The Congress shall assemble at least once in every year, and such meeting shall begin at noon on the 3d day of January,…”) unless they shall by Law appoint a different Day.
Query:Should the primary for senators and representatives be held on the same day for all 50 states (and territories), for example, the first Tuesday in April, May, or June? Why or why not?
