Trump takes 29 percent support among likely GOP primary voters in a Detroit Free Press poll, followed by Ted Cruz at 19 percent and Marco Rubio at 18 percent.

Kasich, the governor of neighboring Ohio who’s trying to lean on support in the Midwest, takes just 8 percent, tying with Ben Carson, who is expected to formally suspend his campaign Friday.

The Ohio governor also trails his three top rivals in another Michigan poll from Mitchell/Fox 2, taking 12 percent behind Cruz at 14 percent, Rubio at 19 percent and Trump at 39 percent.
