This has been answered on many threads.
As Christians, we don't look for world leaders for moral guidance. Every president and those in government are sinful. We try to support someone who will do the better job. Although Trump is hardly the type of person any true Christian would look to for moral understanding, he has encouraged religious freedom, is anti-abortion and pro-Israel---issues that are or should be important to Christians.
That said, Christians who believe that Trump is a "savior" are mislead. And if you place any political ideology equal to your faith in Christ, you are taking a risk.
My wife and I are both Christians and she is a "never Trumper". I am a "sometimes Trumper". I will defend him if he is accused of something he didn't do or say, as I have Barack Obama and Al Gore.
This is why I have no Liberal or Conservative friends since I don't embrace any one political ideology.
