I hate incomplete sets, so I created maps for the 1st and 3rd Districts:
These maps illustrate what a "safe" seat looks like. Neither John Larson (D-CT1) or Rosa DeLauro (D-CT3) have faced a tough election in quite some time (Larson has never had a real challenge to his seat, I'm not sure about DeLauro). This is good for Larson, who was actually beaten by Bill Curry for the 1994 governor's nomination despite being an early favorite (ouch). Indeed, Republicans don't really fund elections in these two districts, and they are completely ignored by the NRCC (National Republican Congressional Campaign).
In both districts, most of the towns that usually vote Republican voted for the incumbent Democrat in 2002 and 2004. This adds further credence to the Incumbent Rule: "All things being equal, voters will trend towards the incumbent." Why else would conservative Granby (which voted for George Bush in 2004 and is represented by Republicans in the General Assembly) go for Larson, one of the most liberal members of Congress, by nearly 17% in 2004?
What's interesting about the map of the 1st District is its unusual shape. I have commented about the odd gerrymandering of districts before, but District 1 is an egregious example. While the combination of Johnson and Maloney's districts into District 5 in 2001 created some uncertainty as to who might win, District 1 (which is largely defined by District 5's borders) was created to reinforce the strength of Democratic candidates there. Why, for example, are the Republican towns of the Farmington Valley (Granby excluded) not included in District 1? Why are small towns like Hartland and Colebrook not in District 5? Why isn't Bristol in District 5? Grographically, this would make a lot more sense.
The 3rd District isn't quite so bad; at least it seems geographically consistent in most areas (the major exception being Middletown). Still, it's obvious that both districts were created with their incumbents in mind.
This can be problematic if said incumbent decides to venture out of the safe confines of his/her district. Take the sad case of Barbara Kennelly, who ran for Governor in 1998. Kennelly had never really faced opposition in the 1st District, and must have assumed that her style of not actually campaigning or paying attention to her opponent would work wonders outside Hartford County. She was, of course, crushed by politically canny Gov. John Rowland (don't blame me, I voted for Groark).
So perhaps the lesson here is that gerrymandered districts make lazy politicians. And who wants that?
If anyone is interested in the Excel files I created to make these maps, here they are:
