A Treat for Politics Wonks

Sean Trende and David Byler have constructed for RealClearPolitics a way to examine the relative strength of the two major parties, using percentages of things like state chambers controlled, governorships, etc.  Their conclusion may be all that interests you, if so here it is:

Even a pretty disappointing GOP year would result in an index that places them above their postwar average and leaves them, on balance, more powerful than the Democrats nationally. (snip) Whatever challenges are facing the Republican Party -- and they are real, if overstated -- this would not be a party in overall decline.

Please feel free to luxuriate in all the minutiae Trende and Co. present, if that's what floats your boat.
