Rs and Ds switch positions re Russian Interference

The difference in how Rs and Ds treat Trump's interactions with Russia in the 2016 election and H. Clinton's interactions is a sham and a shame. My understanding is that

1. Russia engaged in a misinformation campaign, Trump praised Putin, Trump asked Russia in a press conference to look for H. Clinton's email, and Mueller found no collusion.
2. H. Clinton's campaign and the DNC funneled money to a lawyers, who paid Steele for a dossier, and Steele paid Russians for dirt on Trump.

How do Rs and Ds respond?

The Ds state that Trump has committed something terrible and that nothing is wrong with what Clinton did.

The Rs state that nothing is wrong with what Trump did and that Clinton has committed something terrible 

The flip flop illustrates how expediency determines which position each side takes.
