Both Ben Carson and Carly Fiorina have announced their candidacy for POTUS as Republicans as of today. Carson was a renouned brain surgeon, and Fiorina was former CEO of Hewlett Packard.
I saw some of Ben Carson's announcement and he strikes me as a very impressive candidate in terms of appearance and articulation. He's one of the few Republicans who supports stringent tariff protection for the U.S. to rebuild its industrial base.. the only thing that will work.
That's an anathema to the Free Market, Free Trade establishment of the Republican Party.. and it seems likely to doom his candidacy for an early demise.. even though he's bought into the hopeless flat tax and deregulatory aspects of the program. He opposes same sex marriage.. and seems to have no strong opinions on abortion.
Carly Fiorina is a pro life Republican, pro traditional marriage.. but largely in favour of the libertarian economic policies that is leading the U.S. to ruin.
I don't think the core of the Republican Party will trust people who have not held elected office (neither has).. to gauge their malleability to corporate and special interest moulds. Jeb Bush is under their thumb.. i don't think they trust anyone else. They don't really care about moral or social issues. . the prime directive of the Republican establishment is to protect the Global Free Market hegemony.
This is good reference sight of the candidates on the issues.
