I don’t undertand why McRINO is still a Republican.

(CNN) – Sen. John McCain said Sunday that he opposes the thought of filibustering a debate over gun legislation that will probably be brought to the Senate floor this week, despite threats of such action by fellow Republican senators.

“I don’t understand it. The purpose of the United States Senate is to debate and to vote and to let the people know where we stand,” Arizona’s McCain said on CBS’ “Face the Nation.”

A trio of first-term GOP senators – Rand Paul of Kentucky, Mike Lee of Utah and Ted Cruz of Texas – said last month that they will block any gun control legislation that they consider a threat to Second Amendment rights. In a letter to Senate Majority Leader Harry Reid, they wrote that they would oppose a bill that “would infringe on the American people’s constitutional right to bear arms, or on their ability to exercise this right without being subjected to government surveillance.”
