There's a financial component to the 2A (and 1A) that doesn't really exist for the 4A. So the 4A will never have the same level of financial support as the other two.
Is that always going to be true though. As data becomes more valuable, being able to search&seize that data from anywhere anytime sure seems suspect to me.
Don't they also have incentive to protect the 4th as well so that when "they" come to take those arms that they keep shouting "they" are doing, that a strong 4th would prevent them from search&seizing?
I think their view tends to be that the 2nd amendment alone prevents that. I rarely hear them talk about the 4th. However, I am 100% certain that if they stop viewing the 2nd as being so protective, they would become very vocal about the 4th instead.
