I said it before, and I'll say it again. National Carry isn't going to happen anytime soon if at all. Yes, Trump's election has gun owners believing that all our wildest 2A dreams are going to come true, but many are setting themselves up for disappointment. The president does not create law. Although they still are the minority, Democrats picked up aka gained seats this past election. Many state legislatures and representives aren't going to like a blanket law forcing them to do away with the reprocity and carry laws they currently have in their respective states. Democrats will be unified against such a law. Some Republicans will be against it. As you can see from the debates on this site and others, it usually breaks down to about 25%-35% of gun owners being against it. Blomberg and all the other antigun billionaire/millionaires will spend a small fortune to to defeat it, and this isn't something I like to see the NRA going broke trying to push through.
Not only that, but it sets dangerous precedence. There will be a conflict of interest. Some states have stricter requirements than others. These states aren't going to want someone who would be disqualified under their laws (like for having a recent DUI for example) to be allowed get around local laws by having an out of state CCP. The only way to eventually solve this problem will be for the Congress to start adding universal standards.
Some then say we should treat CCP like drivers licenses. To that I say they aren't being realistic. Firearm ownership WILL NEVER be treated like car ownership. We can sell cars privately across state lines, we don't need to do background checks in order to buy cars from a dealer, it's not a felony to drive a car without a license, people do not typically get banned from driving for life for being bad or irresponsible drivers. There aren't strict NFA type laws governing cars and the features and alterations there of making several dozens things a felony on cars like there are on firearms... The two are already treated and regulated differently, so it's so utterly dumbfounding to me that some people actually believe that, if enacted, National Carry would resemble the vehicle licensing model even if it originally started out that way.
