Of course. Without proof or evidence it's all just hearsay. The bits about Russia seeing Trump as a preferable outcome to the election is logical.
The big question is did Trump knowingly benefit from Russian cooperation, and did they promise to reciprocate that cooperation.
I don't think that the second point is well established. Russia's goal of destabilization and not getting Hillary elected was the goal. Not for Trump to carry out their will as POTUS. I don't think they're looking for him to payback favors with presidential power.
But Trump has already done them major favors with the GOP platform re: the Ukraine.
