"Just where do you think Republicans are sitting on this issue?"
Certainly not where the RNC expected to be on October 26, 2020 with a one term president.
"Pres Putin is desperately trying to regain the respect for Russia it once had."
True, but when Russia has power, it has respect. Trump screwed up when was counted on to help Russia start expanding its power base to it's former glory as the U.S.S.R. Without going into long details, that's what that business in Ukraine was all about.
"How deeply has Russia penetrated the Republican Party."
Much deeper than passing out free propaganda t-shirts for people to wear at rallies. I think it will be a while before we, as Americans, find out the truth about the RNC. At first blush, it seems the RNC attempted to pull off one the biggest upsets in the history of the United States, a Unitary Executive, which means one party rule forever.
I doubt we'll ever know how Russia stood to benefit from a Unitary Executive form of government in America but I think it's safe to assume it had a lot to do with the U.S military assisting with their expansion into Eastern Europe and the restoration of the former U.S.S.R.
I've come to believe that the real Quid Pro Quo was between the RNC and Russia, while Trump was the puppet who did the dirty work. I've come to believe that the RNC's agenda (Unitary Executive), and the smokescreen of chaos Trump created, was meant to benefit the RNC more than Russia.
If we, as a country, ever want to ferret out the truth behind this whole inkblot on our society we have to look beyond the end of our nose at the power behind power and who is really pulling the strings. I think it was the RNC.
