Jimmy, a simple question, which you ought to ponder: Look at the Republican Senate's behavior of the last few days, and tell me: Just exactly how deep will they have to plant the knife before you DO decide to vote third party?
You see, the problem with your approach is that we no longer have an anti-gun major party, and a pro-gun major party. We have a major party, the Democrats, who want to take our guns away fast, and a major party, the Republicans, who want to take them away slowly. (And for political reasons don't want to admit it, of course, because they still want our votes, even as they're screwing us.) But they're both taking us down the same road, and the destination is the same. How anti-gun will the Republicans have to get, (Keeping in mind that the Democrats will always be worse.) before your logic no longer applies? And will there be anything at all left of our rights by then? The problem with your logic is that it would apply equally if the Democrats proposed executing us, and the Republicans simply wanted to chop off our trigger fingers. At SOME point, you have to stop voting for the lesser of your two enemies, even if it does mean you risk electing the worse of them.
Oh, and yes, Paul got elected as a Republican, despite every effort of the Republican party to prevent it, including aiding his Democrat opponent. He got elected because he has support coming in from the entire country! The Republican party is a VERY hostile to pro-freedom candidates, as I have cause to know. (Having run as part of a pro-gun slate of precinct delegates, back in '94; The slate members who won were ejected from the Republican convention by police, and the losers certified in their places.)
