The Senates of both Ohio and Michigan have passed state sovereignty resolutions in the last three weeks.
Ohio's resolution passed 19-12 on a straight party-line vote.
Michigan's passed 33-0. Here's the journal entry to prove it (at page 1464). Fourteen of those votes were from Democrats. Three of those votes were from African-American Democrats (namely, Irma Clark-Coleman, Tupec Hunter, and Martha G. Scott).
I have no doubt that they are loyal to their party, and no doubt have at least an affinity for the Democratic Congress and Administration in DC; but I do wonder how two states as similar as Ohio and Michigan could have such different results on the same issue.
Do you suppose that the Michigan Democrats think it's more important to back the people who elected them than to make a show of loyalty to the national party?
