Political Pinheads

Have you noticed that every other sentence in an election year begins with "I think most Americans are thinking/feeling..........

Every single commentator has the insight to how the majority of Americans are "thinking". It's terribly interesting and pretentious at the same time. The reality is they are trying to stare down the "other side" by condescension. They are trying to break the spirit of those that feel differently by convincing them they are in the minority and it isn't worth their time to vote because they are going to be violently trampled by the opposite end of the spectrum rushing to the polls.

My question is, who the heck is "most Americans" and how do any of us know if we fit this criteria thus being able to truly bring to light what "most Americans" are thinking?
