One map shows the national Congressional map after the 2008 election. A mere eight years later, the 2016 elections have resulted in an ocean of red almost everywhere except some coastal enclaves.

One-third of all House Democrats are from just three states: Massachusetts, New York, and California. Note that geographically, most of New York state is actually red, and half of geographic California is also red. About that San Andreas Fault…

As for Wisconsin, two Congressional districts have flipped GOP since 2008 – the 7th from Democrat Dave Obey to Sean Duffy, and the 8th from Dem Steve Kagen to Reid Ribble, and now to Mike Gallagher  – who won the historically centrist district in November with an astounding 62.7 percent of the vote over a relatively strong opponent.

That’s a district that Obama carried in 2008.

And the 3rd, which is represented by Ron Kind, is relatively conservative despite their love of Kind, who advertises himself as a gun-toting centrist Democrat and leader of the “New Democrat” coalition, a presumably shrinking group of reasonable Democrats.

Obama did say he’d make the oceans recede. Well, if the shrinking pools of blue on the maps were the estuaries of the Democratic Party, he certainly did.
