Actually, I'm a fan of everyone voting at the same time. DemocRATS then can't go with the rolling vote across the country to see how many votes they need to win.
In other words, voting in eastern time begins at 10 a.m. to 10 p.m. At the same time, Hawaii starts voting at 5 a.m. to 5 p.m. NO projections, NO polls, nothing. Media silence until the polls close.
As an aside, does anyone wonder why Cuyahoga County (Cleveland), is always the LAST to report in Ohio? (Hint: They're seeing how many votes the Dem nominee needs to win Ohio).
