In reading the editorials and rants from leftists over the recent Supreme Court decision -- that corporations and unions can spend unlimited funds on political causes -- it becomes obvious that the left thinks the Constitution is a bogus document.
The First Amendment guarantees everyone the right to free speech. If you believe an agenda will result in the demise of your corporation, you should be able to speak freely or contribute to causes that will prevent the demise of your corporation.
The real problem the left has is that the majority of union dues are going to support the leftist agenda, even if the dues-payers disagree. All the Supreme Court ruling did was uphold the First Amendment and level the playing field.
