President flexes control in primary state elections

COLUMBUS, Indiana — Elections in the US states of Indiana, Michigan and Ohio on Tuesday made a picture increasingly clear — that President Donald Trump still dominates the Republican Party, and Democrats seem to have the momentum ahead of November's midterm elections.

The biggest test of the president's power came in Indiana, where he backed primary challenges against seven Republican state senators who rejected his redistricting plan in December. Five of the president's candidates won.
