Yes polls are based on the laws of probability and they are pretty accurate as long as they are properly conducted and they have been pretty accurate up until Super Saturday.
Imagine if the tables were turned and Cruz was in Trump’s place. Right after, and I mean right after, Mitt swore to do everything to take him down and aim for an open convention he suddenly under performs all the polls in every contest? You honestly wouldn’t suspect anything. Do you think Mitt holds that much sway with the voters?
I think the vote was more of a reflection of the fact that people are making their minds up at the last minute and Trump’s poor performance at the last debate. It also shows that Rubio has lost a lot of support, and that it has benefited Cruz. Charges of voter fraud make for good conspiracy debate and the intrigue is entertaining. But, no, I don’t take it seriously at this point. Some people have to make excuses and this just happens to be their attempt at an explanation.
