Is "Obamacare" Unconstitutional?

Was it James Madison, the WRITER of the Constitution, who once said (paraphrasing) “I fail to see anything in the constitution saying Congress can take property from one citizen to give to another.”? He certainly should know, being the AUTHOR of the Constitution itself. So everything Obama is doing in an effort to “share the wealth” is not only ILLEGAL, it’s unconstitutional. But then, Obama doesn’t care. He wants to do it, so he’s going to shove it down the throats of the American people if it chokes them, which it will. This woudn’t be so bad if it weren’t for the fact that this government has been violating the Constitution since almost before the ink dried on its signing without significant opposition. (Just common sense)
