Not only that, but Corbyn's Commie voters, in trying to push for a Socialist Government have pushed the centre right Tories way further to the right
Interesting comment actually, though not an accurate one, of course.
I was intending to point out at some time, how during the Blair/Brown/ Cameron times, the political parties were fighting over the center ground of politics.
During the Heath/Wilson/Callaghan/Thatcher years there was clear left-right distinction between the politics of the parties.
Since Major, on into Blair/Brown and Cameron the parties were difficult to separate in a right-left continuum.
Corbyn certainly moved Labour to the left with his traditional Labour policies and May clearly moved the Tories further to the right in her pursuance of a hard Brexit (or any kind of Brexit) perhaps trying to hoover up the UKIP voters.
So while I would agree that May has moved to the right, I would argue that it was Farage (and Eurosceptic Tories) who dragged the Tories to the right, not Corbyn driving them.
Yet despite all that, the centralist parties, e.g. LibDems have not been able to capitalise on the vacuum.
