This was obviously always going to be a huge letdown unless you look at someone's words instead of their actions, have had your head in the sand regarding which foreign nations actually have significant control over US Politics, or you've been binge-watching Maddow since 2017.
There were so many things to investigate Trump with considering his shady business dealings and character, yet the "Resistance" went knee-deep into this Russiagate and now they'll end up with an (deserved for their incompetence) egg on their face. If Trump is indeed a Putin puppet, then Putin is the biggest idiot of all time. What a useless puppet that sends lethal arms and anti-missile tanks next to Russian border (something Obama didn't do), bombs Putin's client state in Middle East (something Obama didn't do), Withdraw from Nuclear agreement with a Russian ally in the middle east, is actively trying to engineer a military coup against Putin's client state in South America now, withdrew from nuclear treaty putting the whole world peace in jeopardy threatening start of a new expensive Arms Race (that could easily bankrupt Russia), and is adding yet more NATO members which is the organization and alliance that is Putin and Russia's biggest security fear. If Trump is indeed installed by Putin....then indeed as Ukrainians say: "Пу́тин - хуйло́" and I would add Путин идиот. On the other hand...one can look at the huge favours Trump has done for another world leader over the last 2 years...including one yesterday just as the election for that friend of Trump is approaching in 2 weeks. Now that's prime puppet behaviour.
There is no doubt that there are certain countries that continuously interfere and meddle in US Politics. Those countries have active lobbies and hold annual gatherings where people of both parties come and give speeches and pledge their alliance to the foreign nation, to the point that going against such lobbies until very recently was a Political suicide (and still perhaps is as we are seeing). Some countries interfere by "donating" millions of dollars into campaigns or Charity associations of said candidates. I can't recall an ARPAC lobby, or oligarchs donating money to political figures...but there are countless examples of Saudi princess, Qatari Amirs and Sheikhs, and Israeli donors, and more donating to American politicians or their circle through a third-party.
This is gonna be Trump's biggest win since the election....just as the enthusiasm among his "base" was massively declining, he took several Political losses...the "Resistance" through their chicken-heads and by putting all their eggs into this Russiagate basket for two years will give Trump a huge boost which could turn out decisive in shifting the momentum just as the election cycle approaches. Because Trump's momentum and energy was way down...Having said that, as of today, I still don't think it'll be enough for him, but lots of things can change until the election time, most important of all perhaps is who the Dem nominee will end up being.
