Let's assume that things turned out rather better for Eurofederalism, and EU integration progressed somewhat more than OTL to a quasi-federal level in recent decades, so that by 2010, fiscal, foreign policy, and military integration has been achieved, at least as a Eurozone-like enhanced cooperation between the continental core nations, and EU institutions have taken a definite quasi-federal character:
EU elections are contested by pan-European party coalitions running on common platforms and candidates, there is an a directly-elected EU President getting (at least some of) the powers of the European Council, the EU Commission is nominated by the President (and Council) and elected by the European Parliament according to the returns of the European elections, the Council of Ministers becomes a legislative Upper House much like the German Bundesrat (or less likely, a US-style Senate) and the Parliament stays the Lower House with all its current powers plus legislative initiative.
Depending on the PoD, Britain (and Scandinavia) may or may not stay in, but the Franco-German-Italian-Iberian-Benelux core does, as well as Central and Eastern Europe. Assuming a butterfly net for the sake of simplicity makes most of the European leaders stay familiar faces, whom do you think the European President, Premier, Foreign Minister, leading Ministers and Parliamentary leaders, as well as main parties and their platforms, would be in 2010, and what speculations could be made about the next European federal elections, on the kind we so often indulge about future US elections ?
I had been tempted to make this topic a double-blind one, but I'm not really good about getting appropriate language, and I did not make it a FH topic, since as things stand now, for the EU to federalize would in all likelihood require at least a couple decades, making it impossible to speculate on European leaders. If someone wants to treat it as a DBWI, he has my fondest blessing. Let's not nitpick too much about the PoD, however, it is not what the discussion is about.
