I don't see the strategic value in denying it happened. It's pretty obvious. I think most people on the right who aren't in the hyper-partisan bandwagon would agree with that.

We should be concerned if it did happened regardless of political ideology.

It'd be much easier to focus efforts on simply discrediting how much it really mattered. Most reports said the Russians spent around $20M on ads which considering both sides campaigns had about a billion each, not to mention the invaluable endless free media coverage over two years most presidential elections take... you can draw your own conclusions.
