Any blame for Russia attempting (or succeeding) anything with Russia before the inauguration, belongs squarely on Obama's shoulders. He was in charge, not Trump.
Plus Hillary hit the "reset" button with Russia so presumably they were good with her.
If the truth were known, I believe both nations have been manipulating elections and media back and forth, for decades. Long before Trump.
It just got picked off the shelf, as a way to discredit Trump. The democrats, media and nevertrump-super-establishment GOP got blindsided by his win.
It is part of communist methodology and Alinsky tactics.
