Nice chart and all that, but this sentence IS the problem.'SINCE 1789'. Didn't take long for political parties to screw up a GREAT Constitution by not heeding the warning of the founding fathers to NOT form these parties, certainly not one or two running everything. We had slavery for a couple hundred years on this continent too, doesn't mean we must keep making the same mistake.
OK. Now you have a data chart. Pick your start date as to when the ‘American People’ started to care about maintaining ‘divided government’ and then calculate the percentages.
The key of course is determining when the electorate became politically ‘aware’ and wanted to prevent single-party control of the Federal Government.
So when is your ‘start’ date?
