You seem naive to his past record - You need to do more homework is this one!
I have not extensively studied his record. I will admit that. I did however watch the piece on CNN about his record and when they compared it piece by piece to other conservative politicians he really had not done anything substantially more offensive as far as "gun grabbing" is concerned. A little pomp and circumstance and blustering for his base in IL, but beyond that no real offensive actions in any circumstances where his vote would have even mattered. Politicians will often vote quietly for something they do not personally believe in if they know there vote will not matter but could be later used against them if they voted against.
I am open to hearing what anti-gun legislation he has personally sponsored or pushed through in his career though.
