The premise of the headline is false (Trump himself is to blame for Comey fiasco).
Comey is a Clinton operative, sleazy, dirty, biased, etc.
To think anybody (media, Congress, FBI themselves) would have established their was no meaningful "Russia factor" in the election, tied to Trump, is delusional and naïve.
Trump himself pushes "matters" such as this into the forefront, by virtue of his style, position, newsworthiness, willingness to take big risks.
