I read earlier this week on FR that some poll had Cruz ahead by 15 points. Apparently polling has fallen into the same junk science hole as alchemy, global warming, and economics.
Or the GOPE needed a pro-Cruz poll, to make plausible an "unexpected" Cruz win (via ballot fraud).
That is the Down’s Syndrome poll of registered Republicans, only 400 of them, taken over a 14 or 15 day period. Just looking at the timeframe you know it’s trash. Then you add in that it wasn’t even of likely voters, and the fact this pollster hasn’t done any polls for 5 years.
