About 60 demonstrators from unions, churches and progressive groups marched today from the North Little Rock Chamber of Commerce to the Little Rock Regional Chamber of Commerce today to press for health insurance reform. The chambers were chosen as march starting and ending points because of the U.S. Chamber of Commerce’s multi-million-dollar effort to scuttle health reform. The LR Regional Chamber, which enjoys a $200,000 subsidy from city taxpayers, is unfriendly to the administration’s plan, and workers rights generally, too.
