The U.S. Chamber of Commerce is the Big Money (K-Street) influence within the Establishment GOP.   The CoC’s President is Tom Donohue.   The CoC has three 2014 demands of Republicans:

• 1.  Keep ObamaCare intact at all costs.
• 2.  Get Immigration Reform and Amnesty Legislation passed.
• 3.  Support Common Core federal education standards in all 50 states.

The CoC has committed to attack any non-establishment Republican candidate who does not support their objectives.   The CoC has pledged tens of millions toward defeating Tea Party candidates.   Karl Rove is one of the SuperPacs carrying out their agenda.  Now Today:
FLORIDA – (Via Liberal Miami Herald)  Jeb Bush, the former Florida governor and a leading contender in the early GOP race for the White House, has fashioned himself as the “education governor.”
But on Friday, Bush went veggie.
“I was the kind of the Eat Your Broccoli Governor,” Bush joked at the Broward Workshop business breakfast where he pointed out that his policies weren’t always perceived as sweet. […]
Bush has advocated for pathways to citizenship and residency for illegal immigrants, enhanced border security and immigrant tracking technology and an emphasis on admitting immigrants based on the nation’s needs, not family relationships with current U.S. citizens.

Bush said immigrants capture the entrepreneurial spirit of America.
“People who come here legally and illegally are the risk takers,” Bush said. “If you’re living in a rural area of Guatemala and you come, you’re a bigger risk taker than those who stay.”
