I'd doubt if Adams will be in any future Irish govt as I cannot see SF in govt down here for another 8/10 years, though when they are in govt it will be as the majority partner, but time will only tell. As for letting "the British worry about the character of their politicians" well clearly through the actions of the Brit dirty tricks dept/SAS/UVF etc the British have very many allegations to answer to down here* but you only apply your selectively morality to the actions of those in Sinn Fein.

Hmmm, isn't this post the kernel of the problem for SinnFein when it comes to turning opinion poll gains into true electoral success. The main message of Sinn Fein is that we have moved on from the past and that what we did back then or who we are doesn't matter. However, this message comes unstuck under the pressure of an election campaign and SF supporters, apologists and politicians revert to the politics of the past and drag allegations of what the British army/government/loyalists/UDA/UVF/unionists did in the past into the debate. The neutrals watching conclude again that the leopard's spot are indeed unchanged and change their mind before casting ballot and SF's poll positions are not reflected in their electoral outcome.
Until SF supporters can come on message boards like this and on TV and radio and debate the issues of the day in Ireland without resorting to referencing the northern conflict then they will continue to have difficulty converting opinion poll sympathy between elections into actual real electoral gains.
