Really?
FYI. There is only one Republican Group. It's know as the Republican Party.
The US Chamber of Commence is an association of businessman, large and small. It is composed of individuals who believe in free enterprise. Many are fiscally conservative and would practice fascism if our system allowed but it is not a political party.
Split hairs and enable all you want. The fact is, the officers of the US Chamber are predominantly Republican. We have to police our own misguided members to be truly effective at pointing out that folly of the Left.
