This district is not in the part of Iowa where Trump will do well. Where Trump will overpeform is the third and fourth districts. Even if Trump wins the state, both the first and second district will still likely go for Clinton by double digits.
No, if Trump wins Iowa, he will have to keep it close in the eastern half of the state, particularly this district. That's where the "MUH BLUE COLLAR WHITES" are that Trump thinks he can win.
When Bush won the state in 2004, he still lost this district by about 9 points.
