I’d like to disagree. strategic voting means you shift your vote to what you suppose to be more majority carrying, which usually tends to go for centrists with quite some neoliberal positions. And they usually manage to put through the same shit as the right on economic issues, or implementing authoritarian attacks on civil rights, like mass surveilance.
It is the same thing in the US. There is the far right extremist republicans and the right wing democrats (by european standards) because they try to cover the supposed center, and everyone left of that still votes for them. So in the end they still get no health care, no social security, lots of warmongering, bad schools and institutionalized racism…
In Germany we get the same bs with people voting social democrats “strategically”, that end up pushing for neoliberal economic policies and authoritarian social policies.
