Just imagine

California recently passed a law in which all candidates for an elective office compete in one primary. The top two finishers then compete in a run-off election in November. Just imagine a single national primary for the office of US President, say in July. Then the top two finishers meet in the November election after a relatively short campaign. If that were in effect now, this election might be between Hillary Clinton and Bernie Sanders. Wouldn’t that be wonderful?
