1. Would you like to pay $30,000 for your new Toyota? Yes 95%
or
2. Would you like to pay $30,000 plus $7,500 extra sales tax for your new Toyota? No 3%
Undecided. 2%
Yes, if you leave out critical information, a poll is bound to be skewed.
How about:
1) Would you prefer to pay $30,000 out of your $60,000 take home pay for your new Toyota ? 5%
or
2) Would you prefer to pay $39,000 out of your new $90,000 take home pay for your new Toyota ? 95%
(I changed your example to use the FairTax rate of 30% exclusive, so it would be $9,000 if the sticker price was $30,000.)
