None of the main parties have any fundamental policies that they can hang their hat on. Left, right, it doesn’t matter. They’re driven by focus groups, not principles."Left" these days has the same meaning as always i.e. tending towards socialist. But "Right" has developed a pejorative connotation, suggesting nativist and racist tendencies.
Both FF and FG are "right" in the sense of being in favour of the "enterprise economy" but without the pejorative connotations. They are "left" in that, as @Purple keeps reminding us they have very progressive tax and welfare policies.
Dare I say it but we seem to have a very civilised and balanced political landscape. Kinda paradoxical as the big three have their roots in violent agitation.
They bend to whatever policy priorities give them the best chance of staying in power.
