Republican presidential frontrunner Donald Trump caused his weekly public stir when he released his first policy paper on immigration. In addition to its proposal to build a massive wall along the southern border and somehow making Mexico foot the bill, it also called for an end automatic citizenship for anyone born on US soil, otherwise known as birthright citizenship.

Donald Trump has been the center of attention since the first Republican presidential debate last week. But perhaps the most significant policy moment in the debates came when two other GOP frontrunners, Florida senator Marco Rubio and Wisconsin governor Scott Walker, announced their opposition to abortion without any exceptions.
