I wonder -are we entering a period in which the Republican Party holds almost uninterrupted control of the House for the next several decades, while the Senate and White House are more competitive, similar to the period between 1954 and 1994 when Democrats dominated that chamber?
People were suggesting the same kind of thing before 2006 happened. The American electorate is volatile and gerrymanders can break surprisingly easily.
The gerrymanders in Florida, Georgia, and Texas seem to be holding quite solidly ever since Republicans first took over the legislatures in those states -and it might prove the case in North Carolina as well.
