Id like to add some prespective. Carrying a gun or owning guns doesnt make you pro-2ndA. Its a well know fact (exc here perhaps) that dems like guns too. They have no problem owning or using them. Their problem is that you can have them too. If Trump came out in unconditional support of general gun ownership without restriction that would be a far better indicator of his true views of the 2ndA. I think tho theres no past history with him to gauge any stmts he might make now.

He has made many statements in interviews to support his position.
