No. When looking at a shadow of a bird flying, you can't understand how the bird is really moving.
In this case, the "centre-left" isn't engaging on the issues that people face day to day. The right parties engage with them, but give fascist solutions. The fact that the problem is acknowledged attracts some people. Others it pushes to not vote. It looks like the population is moving right, but it actually that the electorate isn't representable by the options available.
