What demographic votes for Mick Wallace and Clare Daly?

This not a criticism or an endorsement of either's ideology, just a curiosity.

As far as I can tell Mick and Clare could be described as "Tankies", broadly speaking socialists that oppose the United States and it's allies, favouring the newfound dominance of China, while also siding with Iran and Russia as an opposition to American dominance of geopolitics. Clare herself is a known Trotskyite socialist, as in a legitimate socialist that wants collective ownership of the means of production.

The reality is that their economics would involve completely changing Ireland's economy, increasing our corporation tax rate and turfing out American companies and probably ending up on the belt and road initiative.

Now, here is what I'm interested in, where do Mick and Clare get so many votes from? Outside the Far Left, no one actually supports their programme(not a criticism) but they seem to get far more votes in EU elections than the amount of Irish people on the far left?
