Missouri legislators passed a ballot measure this spring for the November election that would bar the state from taking steps to create a health insurance exchange without approval from voters or the Legislature.  Secretary of State Robin Carnahan this week approved a summary for the measure.  But Lieutenant Governor Peter Kinder KZIM KSIM the language is intentionally biased to mislead voters at the polls.  Kinder says he will file a legal challenge in Cole County Circuit Court forcing Carnahan to change the ballot language and make it more neutral.  He says she is playing political games with Republicans after the Supreme Court ruling last week upholding the federal healthcare law.  Most states say they are waiting to see who wins the Presidency in November before creating these exchanges.
