Politico web site is once again sophomoric and sloppy. It's current poll question asks:
"Would you support a tax-rate hike on millionaires?"
Stupid question. No one is proposing a tax rate hike on millionaires.
Obama is proposing a tax-rate hike on persons (or couples) whose annual income is $250,000 a year. There have been others (Schumer among them) who have proposed upping that to a tax-rate hike on persons (or couples) whose annual income is $1 million. That's not what Politico is asking.
If what Politico meant was "Would you support a tax-rate hike on persons (or couples) who make $1 million or more income a year?" - then Politico's question might be useful.
There is a fundamental difference between a "millionaire" and a person (or couple) who makes $1 million or more in income in a tax year. The tax-rate debate for years has been about the latter (income in a tax year), not about "millionaires.
