Michigan tea party supporters flocked to Republican party meetings across the state this month and won several hundred delegate seats for Saturday's state convention.
Now, activists are positioned to try and push the Michigan GOP further to the right and put hard-core conservatives on November's general election ballot.
The tea party's bid to capitalize on its delegate coup is an important test for a national movement seeking concrete political impact after many of its favored candidates lost in primaries this summer.
Tea party supporters have won Republican delegate seats or other party roles in other states. Their potential impact could be the greatest in Michigan because the convention chooses nominees including secretary of state, attorney general and the Michigan Supreme Court.
