The entire Russian connection is a tactic so the Clintons can stay below the radar. The goal is to place all the attention, on Trump so they can avoid the spotlight on the Clinton-Russian connection. The Clinton Foundation took a large donation from Russian interests, while Hillary and Obama were giving Russia a significant percent of our nuclear stockpile. This is serious enough to look into seeing how Trump accusation has nothing as tangible and documented.
The FBI investigation of Hillary's e-mail server suggested that her server had been hacked by several nations including the Russians, Chinese, Israel, etc. It is very likely, the Russian have her lost e-mails like Trump jokingly suggested. It is easy to download the content of an email server.
What is going on now, is the Clintons and Democrats need to discredit the Russians, even though a few years earlier they were business partners who pushed the reset button. The Trump-Russian connection, gives them a way to deny anything Russian, if the Russian were to release her lost e-mails. They are building up a line of deniability, based on public opinion. They are also showing what they can still do to traitors.
These lost e-mails will be damming for a lot of people, since Hillary was doing US government and foundation business on the same server. These lost e-mails will have correspondence from Obama, as well as a wide range of shady characters from all over the world, who paid to play under the assumption Hillary would be president. Since this is life or death, fake news and the entire swamp, can't stop less they be exposed.
Trump appears to waiting for a certain thing to happen, before it turns the tables. My guess is he will wait until the fall when school is back in session, so he can use this as a civics lesson. Trump Jr's meeting with the Russian lawyer, who turned out to be allowed into the US by the Obama Administration, may have been a trial balloon of a future tactic leading to a reversal. There will be a leak, without a named source, that appears to incriminate Trump or someone close. Fake news will bounce on the leak, without good research. They will smell blood and act. After some research and lots of press negative coverage, the new facts will point backwards causing the beginning of the end of the swamp.
To be honest, people are getting bored with the Russian Trump soap opera. It always promises so much but always disappoints. Trump, the showman that he is, will put together a star studded cast for a new TV political drama, starting Bill, Hillary, Barrack, Jarrad and Rice.
