The Republican control of government is temporary and has failed to significantly improve living standards. 

It is better for Trump to lose in 2020 than to be removed from office through the impeachment process. But it is fair to say that Trump is at risk of impeachment given his weak leadership and unethical behavior.

The Republicans are in poor shape for the 2018 and 2020 elections. Trump has low approval ratings because he is a drama queen and he often makes poor decisions.
