Probably the logic of the ruling party: this president is not great, but if we impeach him now there will be elections and a new president will be elected, this time one from the opposition party. Competent president working for the other party might be considered worse than an incompetent and corrupt one.

I am sure they would vote for impeachment if they had real chances of winning the presidential elections.
