Ganley will stand for the EP himself in the June elections. Irish Times article here.
His economic ideas sound similar to Republic ideas in America - small government, tax-cutting, etc. I'd say that that's very against the grain of political thinking in Ireland today - people are crying out for leadership and expect to be taxed (not that they'll like it). How is Ireland to have sound finances if it doesn't tax more to fill the shortfall (since a huge part of the tax revenue came from consumer spending, which has collapsed).
And it's Dublin that sets Irish tax policy, not Brussels, so how is any of this relevant anyway?
