Not all countries have as much diversity of parties to choose from that have credible chances of winning.
Voters end up settling with one of the two bigger parties
*example, take Portugal. Their FN equivalent is the PNR (they even copied the FN's logo), but they have almost no support and no represnatives elected.
So most Right wingers will either vote for the vanilla Center-Right PSD or the for vanilla Right-Wing CDS-PP . (both PSD and CDS-PP have formed coalitions together to outnumber the Socialists in the past 40 years)
Not all countries have FPTP. I.e. you have a point for, say, the UK, but not so much for Germany, the Netherlands and tons of other countries with popular vote based systems.
