A Missouri initiative to re-instate campaign contribution limits has cleared its final legal hurdle to appear on the November ballot.
The state Supreme Court on Monday turned down a request to hear a challenge of the proposed constitutional amendment.
The proposal known as Constitutional Amendment 2 would limit contributions to candidates to $2,600 per election and cap donations to political parties at $25,000.
Missouri's previous campaign contribution limits were repealed in 2008. Since then, some donors have routinely given five- and six-figure checks.
