A lawsuit seeking to block a proposal to expand Medicaid from reaching the August Ballot has fallen flat.

Judges at the Missouri Supreme Court deciding not to take up the lawsuit Wednesday pushed by a number of conservative groups, including United for Missouri, who claim the measure appropriates money without providing a new revenue source.

The measure dubbed Amendment 2, would extend eligibility for Missouri’s Medicaid program to adults earning up to 138% of the federal poverty level, or about $17,600 for an individual or $30,000 for a family of three.

Currently the program’s threshold for parents is one-fifth of the poverty level, one of the lowest in the nation.
