Like Trump, Sinn Féin carried on as if the election had been stolen from them.
Like Trump, they publicly vented their contempt for the institutions of their country - who can forget Davy Cullinane at the RDS deriding the 'Free State' and shouting "up the RA"?
Like Trump, they abused social media to undermine their political opponents as in the Twitter hashtag #NotMyTaoiseach.
Like Trump, Mary Lou McDonald called for nationwide rallies to force SF into government.
Five months after the election, SF TD Thomas Gould, still in Trumpian denial, tweeted: "Mary Lou McDonald is my Taoiseach."
It was not until June that Mary Lou McDonald publicly conceded Sinn Féin had no entitlement to be in government.
