Doesn't seem to be doing his poll numbers any good. He came off very badly in the Pat Kenny debate attacking Higgins, who dealt with him rather well. I see Ni Riada is trying a dig at Higgins as well today, over this "jet to Belfast" thing. But none of it really sticks.
Edit: On Casey, he's going on about Higgins' dogs again today, both on the cost of grooming and on their breed. The first point is completely immaterial - there's no way Higgins would be so stupid as to put that expense on the taxpayer, and he can spend his salary anyway he pleases - and the second is the weirdest bit of faux-nationalism I have seen in a while
