Or are we in the 'policy-free zone' that constitutes so much of Irish politics? If so, if there were no fundamental differences between Fine Gael policy and George Lee, then what we have here is a case of someone who resigned because he didn't have enough input into policy that he didn't disagree with anyway.
Or maybe there's something more provocative. Maybe George had nothing left to say on economic policy. Go back to his 10-point plan. Read all the points he makes. They have, for the most part, already been take up by Fine Gael (some of them, like point number one, was already party policy) or has been acted upon by the Government. His 10-point plan that he ran on in the by-election is pretty much last year.
Maybe he just couldn't think up another 10-point plan to impress upon his party, the Government and the nation.
Maybe he just lost his . . er . . edge.
