He wants all "assault weapons" outlawed but then sneaks around and buys himself an AR-15.
Then when he's caught, he comes up with some bullsh*t story about doing it for research or something.
The good part is that this will endear him to all Democrats because they love liars whether they're good at it or not. A lie is an acceptable attempt to "stick it to the man" even if it's a laughable lie like this one is. They still love it.
I think we can expect him to be elected to and occupy some high political office as a Democrat after this if he ever desires to run.
