According to a recent Pew Research Center poll, less than a quarter of all Americans believe raising taxes on the wealthy will harm the economy.
And for comparison's sake -- roughly the same percentage (22) of people believe in the Loch Ness Monster. Significantly larger portions of the nation believe in UFOs and that George W. Bush was a great president.
The Republicans have lost on this issue. Full stop.
