On Thursday's Closing Bell on CNBC, Rob Reiner repeated his charge that Donald Trump's supporters are "not all racists, but there is a strain there." Host Bill Griffeth wondered, "Don't you think just people are angry — they're angry at Washington; they're angry at their boss?" Instead of immediately pointing to "racism," Reiner admitted that "there is a big chunk of Trump supporters who are very upset at the income inequality." However, he added that "there is a strain of racism that's there — because when you go to the Sanders rallies, there are no racists at those rallies!"

The media is still having trouble understanding the Tea Party movement and what it is protesting, even though its roots are clear. 

On Feb. 19, 2009 during CNBC's "Squawk Box," Rick Santelli made his famous rant heard around the world, calling for a so-called tea party-style revolt. And that helped fuel the growth of a Tea Party movement that has resulted in more than 600 protests this April 15, 2010.

Santelli's call for protest wasn't about high taxes. Instead, it was a cry against the Obama administration's plan for a taxpayer-funded mortgage bailout. The very beginning of the tea parties was about bailouts and the growth of government.

But the Associated Press still seemed to miss the point about worries over an overspending government in an April 15 article by Calvin Woodward about the Tea Party rallies. In that report, Woodward defended Obama's tax policies.

"Lost in the rhetoric was that taxes have gone down under Obama," Woodward wrote. "Congress has cut individuals' federal taxes for this year by about $173 billion, leaving Americans with a lighter load despite nearly $29 billion in increases by states. Obama plans to increase taxes on the wealthy to help pay for his health care overhaul and other programs."
