This is another in a series of pictures showing what this year's blue wave looks like. So far, I've done New England and these Mid-Atlantic states individually. Each congressional district has equal size here. I know I said on Sunday that Ohio would appear today, but Ohio should appear tomorrow. (Really.)

This is something new series of pretty pictures showing what this year's blue wave looks like. So far, I've done several individual states, but here is the entire New England region. (I finally figured out how to merge shapefiles.)

Here's how things stood before the 2006 election.

The green represents Bernie Sanders (who caucused with Democrats), and there are five red districts.

Sad to see so much red in a place like Connecticut...

Can't do much better...

This is the fifth in a series of pretty pictures showing what this year's blue wave looks like. So far, I've done Pennsylvania, New York, Maine, and New Hampshire.

Vermont only has one district, so a cartogram by district isn't very interesting. It's also debatable whether Vermont had a blue wave. Nevertheless, I don't want to skip Vermont, so I'm posting it on a travel day.

The green represents independent congressman (and senator-elect) Bernie Sanders, who caucused with Democrats.

This is the second in a series of pretty pictures showing what this year's blue wave looks like. I started with Pennsylvania. New York is next, because the expansion of New York City is so spectacular. Cross-posted at MyDD. For more maps, I recommend ManfromMiddletown's diary on New York.

These cartograms shows New York with each congressional district having equal size. This gives a better view of the equal importance of heavily Democratic urban districts and slightly Republican rural districts.

Wow! Look at how blue New York already was once you have a clear view of the twelve Democratic districts of New York City! But it gets better...

This is the first in a series of pretty pictures showing what this year's blue wave looks like. I'm starting with Pennsylvania because I live here (in the 2nd district) and volunteered a fair amount for Patrick Murphy in the 8th District. A cartogram is a map in which the shapes of regions are skewed so that there areas match some statistic. For example, Wikipedia's article on the 2004 election shows the Bush/Kerry vote by county with each county's area in proportion to its population.
