Not surprising that the only people who think Sanders is more electable than Clinton are foreigners who have no idea how Americans think.
Sanders has had literally ZERO negative media coverage. The Republicans are all praising him because they want a geriatric extremist whose campaign is run by hapless amateurs to be their opponent. Despite all this, he's on average doing the same or only slightly better than Clinton.
Maybe "trillions of dollars in spending" and "raising taxes on the middle class" are winning arguments in Soviet Austria?
