In light of my new interest in gun ownership (see previous post here), I looked into McCain's 2nd Amendment record. Here is a Chuck Baldwin (Constitution Party Pres. candidate) quote about him from GOA.
Let me say it straight out: a John McCain Presidency would be far worse than a Barack Obama Presidency. With a Democrat in the White House, conservatives and Christians suddenly find their principles and are able to offer resistance. Put a Republican in the Oval Office, however, and those same people become blind, deaf, and dumb to most any principle they profess.
Nowhere is McCain's chicanery and duplicity more jeopardous than in the area of the right to keep and bear arms. On issues relating to the Second Amendment, John McCain is a disaster! For example, the highly respected Gun Owners of America (GOA) rates McCain with a grade of F-. McCain's failing grade is well deserved.
Now one might be able to say that he is biased as he is running against McCain. Fair enough. Let's let the evidence speak for itself. You can see a sample of his voting record here.
