He's done the Remain campaign no end of good by his actions.
Interesting thing about the polls taken after this tragedy versus the polls taken immediately before...
If one looks at them, and compares the numbers, support for Remain hasn't gone up... (The two most recent polls have Remain on 44% in one, 45% in another...unchanged from polls taken in the days before the murder...)
What happened was that the momentum that was shifting the
undecided vote to Leave was reversed, and that percentage moved back from Leave to
undecided....
Putting the race back into a within-the-margin-of-error toss up....
There has been no significant increase for Remain...
How the folks who were moving to Leave but moved back to undecided in the immediate wake of the shooting will vote, (now a week later from the initial emotional impact of the event) is what will decide the outcome....
