The only person running currently that fits your criteria is Duncan Hunter.
Republican voters still get to decide this. Money only buys elections when people act like sheep. If 80% of Republicans are indeed seeking a conservative, we can nominate one. We can nominate Duncan Hunter. The money players won't like it and are trying to convince us only Rudy, Romney, or McCain can win. Hogwash. 49% of people will never vote for Hillary. Only 60% voted last time and turnout was the difference. My belief is Rudy would push turnout down. There might even be a third party, splitting the vote. Give Americans a chance to vote for a candidate who WILL secure the border and watch what happens to turnout. Americans want their government to fulfill it's most basic responsibility.
The primary responsibility of the U.S. government is to protect the territorial integrity and people of this country. They have completely abdicated this responsibility. Both parties have been complicit in this. We are being told it is not possible to control our borders, enforce our laws, and thereby control our destiny as a nation. Hogwash. We are being sold out by corporations intent on importing workers for jobs that can't be exported with the taxpayers paying the true costs, financial and human. If we act like sheep and don't stop the inundation across our borders, we will lose our country without a bleat.
