Russia became a partisan thing when they interfered in the election on behalf of Trump. I remember when Putin first acted in Crimea in 2014 it was the Republicans who were more hawkish and criticizing Obama for not reacting strongly enough.
From the other side of it, at least it's a good thing most the left finally realizes that Russia is run by bastards. The tankie crap would be so obnoxious right now otherwise.
Considering how the Republican Party switched their position on Russia on a dime after Donald Trump's nomination and election in 2016, it's obvious their previous opposition to Vladimir Putin was always only skin-deep.
