Whether or not you agree with Donald Trump it seems that the mainstream media and GOP establishment has successfully squashed the issue he brought to the fore: ending Muslim immigration. At a time when the DHS is cutting back on surveillance operations on the southwestern border and POTUS is visiting a Virginia area mosque with clear ties to Al-Qaeda and the Muslim Brotherhood; the GOP candidates have gone silent on this issue.
The number one threat to American sovereignty and security has been buried beneath a barrage of cable news sensationalism and GOP shenanigans. Rubio is clearly an open borders advocate and Cruz stance on issues concerning immigration, specifically the HB1 Visa program, is questionable at best. Trump in all his bombast and flip-flopping still has it right on immigration. Socialism, which creates an atmosphere ripe for widespread illegal immigration, has racked Europe and caused it to be overrun by hordes of Muslim savages. Americans are potentially facing a similar threat.
The Iowa Caucus was co-opted by the cable news media and the GOP establishment and turned into a personality contest rather than a serious discussion on the threat facing America.
