In general, gerrymandering makes incumbents less secure, not more secure... so it's not really the fault of the system that districts are polarized.
From the dictionary: Gerrymandering is "to divide (an area) into political units to give special advantages to one group"
How could you say it makes them less secure in general? Isn't the reason gerrymandering exists that it makes them more secure?
In some ways moderate districts DO hold power, the views of the median house/senate member are nearly always the best represented in Congress in terms of what legislation passes.
Depends on the issue, but I think you're underestimating Congressional leadership's power to get things to a vote or deny legislation a vote at all.
As for why the moderates don't control both parties, it's because there aren't actually very many moderate districts at this point.
I think the purple district-by-district national election map you'll see every four years would say differently. Most districts have a healthy amount of liberals and conservatives, many willing to change sides multiple times during their lifetimes (at least in terms of how they vote).
Because the point of gerrymandering isn't to make individual congressmen secure, it's to give your party the maximum number of seats from the available area. An effective gerrymander makes it so that if you have 10 congressional districts, you make it so that even if the vote on the whole is split 50-50, the goal is to make it so you win 9 out of those 10 districts 51%-49% and then lose the 10th district 99%-1% or whatever. In effect you've given yourself 4 extra seats, and 90% of the representation while only really having 50% of the vote. Because of the benefit of winning lots of tight districts as opposed to a few safe ones, gerrymandering in a general sense tends to actually weaken incumbency. The reason why incumbents still get re-elected so much has more to do with lots of other things like fundraising, name recognition, party organization, etc.
As for the overall polarization of districts though, it most certainly is a problem. (just not one created by the parties, it appears to be a sociological one) The number of moderate districts has been rapidly declining over the last 40 years, and the trend appears likely to continue. They are in the decided minority now. Generally political scientists like to look at presidential election results as they involve the best samples and best information for voters, and the number of landslide districts (where either Obama or McCain won by more than 20 points) are almost an outright majority of all congressional districts nationwide according to Slate. So really, most districts DON'T have a healthy mix.
I personally have always thought of a landslide as being something less than 20 points, so heavily polarized districts are probably around the 60-70% area at this point... and they will likely continue to go up. So, I guess your fundamental point about super polarized districts electing more radical members of Congress is true, I just disagree on why. In my opinion it's more a case of 'we have met the enemy and he is us'.
