If you go here, you can see a video of a "heckler" ask good old Mitt Romney (a.k.a. R Money or R Mizzle) if it's patriotic to "stash your money in the Cayman Islands".
First of all, this lady is not a heckler. Not for asking a legitimate question. As a matter of fact, I wouldn't be surprised if she was a Romney Campaign plant, to show the more "human" side of Romneybot. To highlight that he can "roll with the punches". The whole thing just seems so contrived, too. Remember the "don't taze me bro" kid? That's how you deal with hecklers. Not with gasps of mock outrage.
Secondly, Romney was very well prepared for that question (a little too prepared) with a well written, concise answer that would appeal to the conservatives. He even got to display his artificial candor and make an attempt to "connect" with people with his little joke about it only being fair for him to "take his shots."
This is not heckling, this is political strategy. You identify the questions you're not comfortable answering. Then you answer them in a controlled environment, like a staged town-hall event. The media (and today, social networking) runs with the story and it temporarily makes headlines. The story has been covered.
If the story reappears, say in a primary election, it's old news. It no longer makes headlines because media organizations aren't interested in selling the same old stuff. They want new material. This story has already been covered. The candidate has effectively buried his skeletons under the heap of media crap.
This "heckler" (Romney plant) was essentially asking, "Mr. Romney, why are you so great?"
I found it interesting that the last words out of Romney's mouth in that video was "I pay my taxes, and not a dollar more", meaning that he is taking advantage of every shelter and loophole there is and he feels that he is not going to pay a penny more. While Bill Gates and Warren Buffett feel that they pay too little. (Net worth of 56 billion and 650 million respectively)
Greedy parasites like Romney's response is exactly why taxes for the rich need to go up.

This is what Romney's attitude on taxes is doing to this country, btw.
