The entire premise of this thread is bogus, the typical Obama Derangement Syndrome. Take something he said, twist it then pile on lots of conspiracy theories and throw in some racism for fun.

Obama answered a citizen question in Cleveland about Washington dysfunction and Citizens United. He mentioned several ways to improve the dysfunction and take big money out of politics. He mentioned in his answer that in Australia and other countries there is mandatory voting. He never proposed such a measure here. He also mentioned gerrymandering and other issues with meaningful elections. But go ahead and get angry and the POTUS who speaks much more clearly than you listen or comprehend.

In Australia, and some other countries, there’s mandatory voting. It would be transformative if everybody voted. That would counteract money more than anything. If everybody voted, then it would completely change the political map in this country, because the people who tend not to vote are young; they're lower income; they're skewed more heavily towards immigrant groups and minority groups; and they're often the folks who are -- they're scratching and climbing to get into the middle class. And they're working hard, and there’s a reason why some folks try to keep them away from the polls. We should want to get them into the polls

If you read somewhere in that comment that he "wants to make a law you must vote" as the OP wrote and so many of you believe, it is a sad commentary on your ability to understand beyond what Fox News tells you to believe.
