It’s all just a big political calculation. Obama knows that he will not be removed from office as the Senate won’t allow it (even a Republican controlled Senate). If he is impeached by the House, he will turn around and cry that he is a victim of White male racists—his base will eat it up. A few Blacks are getting wise to his game, as even they see that importing tens of millions of illegals will not help them—unfortunately, there are not enough of these and they may just not vote (vs. voting Republican).
Make no mistake, Obama is intent on creating tens of millions (maybe up to 100M) of new Democratic clients (voters) in his remaining time in office—legal or illegal. Forget Obamacare—stacking the deck to put conservatives in permanent, minority status will be his REAL legacy.
obama knows how much impeachment hurt Bill Clinton (NOT) ... and he doesn’t worry about it at all, it would be a legacy building badge of honor to him.
Stacking the deck for the future, as you point out, is his goal. And that tactic fits nicely with his Cloward-Piven and Allinsky training.
