29 Republican Governors must be wrong.
Instead of joining the other governors, Snyder sent his own letter to Upton, the association said on its website.
Snyder has said the state will prepare to implement the 2010 Obama health care legislation unless or until the law is changed or struck down by the courts.
The RGA's count of Republican governors signing the letter included the governor of Puerto Rico, a territory.
Michigan's Republican Attorney General Bill Schuette is among those suing to have the Obama health care legislation declared unconstitutional.
Rick, please just join Mark Brewer's Party already.
