McCain-Feingold To Unravel?

According to this article the possibility exists.

The biggest potential change would come if the court grants corporations the
same free speech protections now granted individuals under the First Amendment of the U.S. Constitution

Hmmm. I don't recall exceptions to the first amendment when I read it. My understanding from my Civics class was that the first amendment was to insure political speech was free and unimpeded. It seems to follow that McCain-Feingold could be in trouble. Of course, logic doesn't always seem to be present as one reads court decisions.

Just a thought.
