On June 24, the Bipartisan Policy Center issued a report, “Governing in a Polarized America: A Bipartisan Blueprint to Strengthen Our Democracy.” One surprising recommendation is that all states hold congressional primaries on the same day in June. The Report does not discuss why June was chosen. Currently, congressional primaries are held over a six month range, from March through September.
The Report does not say whether it believes Congress should legislate a uniform primary date, or whether the states should simply be asked to agree. Bills in Congress to regulate the dates of presidential primaries have been introduced starting in the 1980′s, but none has ever come close to passing. It seems unlikely Congress would ever pass a bill to regulate the date of congressional primaries.
The Report is vague about what type of primaries are best, and simply concludes that primary turnout should be encouraged.
