In this column, Michael Barone discusses the hypocrisy of the Left on the issue of protecting speech.

Currently 43 Democratic senators are so-sponsoring the constitutional amendment introduced by New Mexico’s Sen. Tom Udall to amend the First Amendment so that it no longer protects political speech.

“To protect the integrity of the legislative and electoral processes,” the text reads, “Congress shall have power to regulate the raising and spending of money and in-kind equivalents with respect to federal elections,” including limits on contributions to and spending by or against candidates. The same power is given to state governments.

There are other terrible examples of this effort to silence others, Barone writes.

Read the Lois Lerner Internal Revenue Service emails that someone somehow didn’t manage to destroy, and you see a liberal self-righteously determined to silence opponents.

Similarly, the runaway Democratic prosecutors in Wisconsin, since slapped down by a state and a federal judge, sought to intimidate people who wanted to advocate policies supported by Gov. Scott Walker.

Once again we find that the ‘tolerant’ Left are the least tolerant among us.
