The folks over at “The Fix” blog on The Washington Post
website offer an especially gloomy look at the impact of gerrymandering and the
power of incumbency and they concluded that nearly all House members are “becoming
mostly immune to the day-to-day sways of public opinion.”
That’s because only 30 House races have any
right to be called a “race” of any sort this year, according to The
Fix. That’s 30 out of 435. That’s 6.8 percent of the entire House.
The Post’s  Election
Lab model
found that that there are 405 races where the incumbent or
front-runner has a 90 percent (or better) chance of winning at this point in
the election.

The Cook
Political Report 
rates only 43 seats as toss-up or leaning
Republican or Democrat — or 9.8 percent of the House. The Rothenberg
Political Report
 counts 51 seats as competitive, 11.7 percent
of the House.
