"In most countries it is called run off elections and makes sense - it first gives people a chance to express their preference and then gives them a second chance if their first choice does not face any real chance of being elected..."
62 would not invite a runoff, but merely drop all minor party candidates after the primary and leave the general election to the two corporate parties...that "makes sense" to the republican and democratic parties which will benefit if this thing passes, but makes no sense at all to anyone who supports -at least in theory if not in practice - democratic choice, and not simply democratic party politics...
