"Republicans support impeachment by a 48-31 margin, a number which Tom Jensen, our pollster, points out is almost identical to the 51% of Republicans who think Obama was not born in the United States. Says Tom, "The lunatic fringe of the GOP is basically half of the party’s voters" - in which case, it's really not a "fringe," is it?
Strangely enough, our survey also showed that 14% of Democrats say they do, too (78% are opposed). That last finding struck us as quite unexpected, so Tom ran an additional crosstab. We learned that among those who claim they support impeaching Obama, 11% approve of his job performance! Like peanut butter and mayonnaise, these two things clearly do not go together. Our only explanation is that some portion of voters simply aren't familiar with the term "impeachment" actually means."
