dia daoibh ar maidin

Bhí mé ag léamh alt ón tsuíomh "Tuairisc.ie" agus chonaic mé an friotal seo ag deireadh ailt:

"ach...aithne ná aithne ná aithne níl agam ar Chaitliceach ar bith atá le vóta a thabhairt don DUP..."

I was interested in the first part, is putting the same word either side of "ná" another way to emphasise it? Also the part where it says "...aithne níl agam ar..." is throwing me. I'm guessing this is just another way to structure the standard "Níl aithne agam ar..." but if it is what is the point of this particular structure? Does it emphasise? Or is it just structured this way because of the way the author repeated the word "aithne" before?

I was once told:
Níl X agam = I have not X
X níl agam = I have not even a single X
X ná Y níl agam = I have neither X nor Y

So I'd translate Aithne níl agam ar as I have not the slightest knowledge of

I can't say anything to aithne ná aithne ná aithne.
But I guess it doesn't add much to "not the slightest".
