Rep. Justin Amash appears to be safely situated to retain his congressional seat, according to a new internal poll showing the Michigan Republican holding a 22-point lead over his primary opponent.

The poll, conducted by Wenzel Strategies of 705 likely Republican voters in Amash’s district, found the libertarian-leaning incumbent leading the GOP establishment-preferred businessman Brian Ellis 56 percent to 34 percent, with 10 percent still undecided.
