The constant negative narrative hasn't effected Trump in the slightest bit. Republican leadership still lick his boots. His fan base will never, ever want to kick him out of office, they believe the Trump/Russia story is "Fake News".
Hasn't affected him one bit except it has. You want me to go down the list?
1) Trump's approvals have been trending downward
2) Every special election that we have had has shown a consistent 14-15 point swing towards the democrats. If that holds for the midterms, the Dems will take back the House.
3) Trump has had both of his travel bans struck down because he keeps fucking up his own narrative about them
4) Trumpcare is widely unpopular to such a degree that the GOP wants absolutely nothing to do with it
5) Democrats have been getting record numbers of donations as a result of Trump and his fuck ups.
6) Fox News has gone full-breitbart and as a result has now dipped in ratings below CNN and MSNBC.
7) Constant leaks are happening from the IC, the FBI, and even the White House itself, because Trump as a leader does not inspire confidence. When Comey was fired, the Washington Post LITERALLY had 30 (yes THIRTY) different sources from the FBI all lining up to talk to them about the firing. Think about that for a moment THIRTY DIFFERENT SOURCES.
Like, yes Trump's hardcore fanbase would literally jump off a cliff if Trump told them to, but Trump and the GOP didn't win last year off of just those voters.
