Lets at least know the facts here. Unauthorized immigration numbers from Mexico have declined during Obama's administration (5.6 million in 2014 compared to 6.4 million in 2009) and have been lower than under President Bush. Simultaneously, deportation numbers have generally increased when compared to his predecessors with the exception of FY 2015. I mean look at the data.... I would argue that the Obama administration has been the most effective ever at curbing illegal immigration.

I do not disagree with you at all on the absurdity of his deportation pledge or free college education for that matter. As far as income equality, I think measures can be taken to achieve more income inequality. For instance, expansion of the earned income tax credit while you slowly taper up the minimum wage. You are kind of taking "income equality" to its literal extreme, which I do not believe is the position of mainstream Democrats.
Last, my definition of "assault rifle." Admittedly I am not a gun guy and am not super familiar with the terminology, but I would think something along the lines of a long weapon, that's clip exceeds x amount of rounds (insert your number here -- but something around a standard handgun), and the ability to repeatedly discharge said rounds by simply pulling the trigger i.e. not bolt action. A more expansive background procedure is slightly more difficult. I would like to see some form of mental health screening, especially with the purchase of handguns. If I go to buy a handgun I should have to waive HIPPA. This would be unpopular and goes beyond your initial question, but if someone purchases a gun I think they should also have to obtain liability insurance with penalties for not doing so and a proof of insurance requirement at purchase.
