US Meat Labelling Laws

Q129: When will the US Federal government repeal its country of origin meat labelling laws?
Before September 1st, 2015: 40%
Between September 1st, 2015 and December 31st, 2015: 25%
Not in 2015: 35%
(A partial repeal counts, as long as the requirement for retailers to indicate country of origin is eliminated)

The US currently requires retailers to indicate the country of origin for meat products.  Canada and Mexico have won a WTO ruling against this practice, and have threatened to impose retaliatory tariffs if the US federal government does not repeal it (see story here).  The US House of Representatives Agricultural Committee Chairman has said that he will introduce a law to repeal the requirements, and that he expects a vote in early June (see article here).

A wide variety of outcomes are possible for this question,  However, it seems to me like the US will likely either repeal the requirements relatively quickly (before September) or not do so at all this year.
