Through the magic of his math and numbers, Nate Silver has proved conclusively that modern American voters have a very secret shameful prejudice they will only indulge in the privacy of the polling booth: they do not like Republicans. Sure, they will tell a pollster on the phone, "Yes, I am definitely voting for that nice Republican. Some of my best friends are Republicans!" but then they will still pull the lever for the Democrat when nobody is looking. This is why so many Republican candidates underperformed in 2006 poll projections. Americans must have an open, honest dialogue about party affiliation so that our poll projections can be more accurate. [FiveThirtyEight]
