It's tough to approximate a 2-party system onto the French election.
So what I did was add up the totals of Hollande and Melanchon (two major leftist candidates) and create a "Cook PVI" for each region of France.
This doesn't take into account Marine Le Pen, a strong third party candidate, but if you're curious, she was much stronger in the Northeast and Southeast of France and much weaker in the Center West, Northwest, and Paris Suburbs.
Paris hasn't reported yet, but it's too small to fit on the map anyway.
One amazing thing (compared to the US) is how close all the regions of France are compared to the national totals.
If there were a French electoral college, every region but Alsace, Champagne, and Corsica (France's Oklahoma, Idaho, and Utah) and Limousin and Midi Pyrenees (France's Vermont and Massachusetts) would be a "swing state," having a PVI of less than 5.
Here's the map (colors are flipped, as in Europe red=left and blue=right). Note that Alsace is such a dark shade of blue it appears to blend in with Germany, ironic if you know European history.
6:43 PM PT: Unlike in the US, overseas colonies can vote.
In Guiana, the Left is 12 points higher than the French average, but it's all at the expense of third and fourth parties.
In Guadeloupe, the Left is 23 points higher, but only 4 of those 23 are taken from Sarkozy; most are from Le Pen.
In Martinique, it's very similar to Guadeloupe, but a few points more conservative.
