Javier Solano is here and it looks like he is here thinking to broker some sort of a deal. But the Yuschenko side has said that the deal they will entertain is the transfer of power.
But this doesn't seem to be an absolute position, There is an idea being batted around by the opposition that they would be amenable to holding the election again but with some strict controls this time. One of the ideas is that the people would be allowed to vote by showing their internal passport. That passport would be stamped showing they had voted. If, of course, they were to try to vote again, the passport would show they already had. The thinking is that this would be one way to prevent the widespread fraud of the other elections.
The point is that the Yuschenko sides seem to be interested in a legitimae vote for president. Of cource they are confident that that vote would give him the presidency. They are probably right.
