Today I will be voting for the best candidates, not for the 'best party'
If I lived in, say, Germany, I would have a party to vote for. If I lived in northern Germany I would vote for Angela Merkel's Christian Democratic Union, and if in the south most likely for the Christian Social Union.
These parties are members of the European People's Party, the biggest bloc of parties in the European Parliament. Fine Gael belongs to that bloc. There are quite a few parties in the EPP that I could vote for. Fine Gael is not one of them because Fine Gael has not been a Christian Democratic party, or anything like it, for quite a while now, and under Enda Kenny has moved even further from its roots.
That is not to say I would not vote for a given Fine Gael candidate, but the vote would be for the candidate, not for the party. I won't be voting for any party, per se.
