That would be Republican Bruce Bartlett, who worked in both the Reagan and Bush 41 administrations, as well as being a former staffer to Ron Paul:

On March 16 the Tea Party crowd showed up for yet another demonstration on Capitol Hill in Washington. Curious about the factual knowledge these people have regarding the issues they are protesting, my friend David Frum enlisted some interns to interview as many Tea Partyers as possible on a couple of basic questions. They got 57 responses–a pretty good-sized sample from a crowd that numbered between 300 and 500 people.

Tuesday’s Tea Party crowd, however, thought that federal taxes were almost three times as high as they actually are. The average response was 42% of GDP and the median 40%. The highest figure recorded in all of American history was half those figures: 20.9% at the peak of World War II in 1944.

Wow – could the tea baggers be even more wrong? Of course they could:

Tea Partyers also seem to have a very distorted view of the direction of federal taxes. They were asked whether they are higher, lower or the same as when Barack Obama was inaugurated last year. More than two-thirds thought that taxes are higher today, and only 4% thought they were lower; the rest said they are the same.

As noted earlier, federal taxes are very considerably lower by every measure since Obama became president. And given the economic circumstances, it’s hard to imagine that a tax increase would have been enacted last year. In fact, 40% of Obama’s stimulus package involved tax cuts. These include the Making Work Pay Credit, which reduces federal taxes for all taxpayers with incomes below $75,000 by between $400 and $800.

So the Tea Party, and the Republicans that support them, are actually opposing lower taxes. Way to go guys! You really are on the losing side of history.
