Beyond the obvious Michigan battle between mainstream
Republicans and tea party types, today’s (tentative) big vote on Medicaid
expansion in the state Senate has unveiled another major split – Michigan GOP
Vice Chairman Victor Diaz vs. Gov. Rick Snyder.

On Facebook, Diaz today is urging fellow Republicans to call
key senators and “encourage them to stay the course (or switch their vote). …
Do not let ‘Snydercaid’ pass the Michigan Senate!”

Snydercaid is apparently now the disparaging moniker used to belittle the governor – a Michigan version of “Obamacare.”

Diaz is imploring conservative stalwarts to call Senate
Majority Leader Randy Richardville and three GOP senators who may be teetering
toward support for the Medicaid bill.

“Let them know that we must say no to Snydercaid!” Diaz
concludes.

UPDATE: Apparently party Chairman Bobby Schostak, a
Snyder pal, didn’t place a call to Diaz and tell him to knock it off. In his newest
FB post, Diaz continues to take aim at the GOP governor: “At the Senate
chambers where the Republican caucus is twisting arms to get Sndyer’s vote on
Snydercaid passed. I think the ‘Hastert rule’ is in question! Just say no to
Snydercaid!”
