Donald Trump uncertain over endorsement

Former President Donald Trump exposed his uncertainty about Ohio’s U.S. Senate candidates at a rally last summer when he polled the crowd to see who garnered the most enthusiasm.

But he did not announce his ownpreference — and months later, not much has changed.

Most contenders in the GOP primary have made Trump a central part of their campaigns, and it’s no secret that they desperately want his endorsement. But associates of the former president say he has issues with everyone in the field, from questions of loyalty to concerns about their ability to win a general election.
