Biggest RINO and DINO presidents 1990 to now?

[Southern Senator North Carolina Yankee]

The whole concept of a RINO or DINO comes about because of "the other teams turf". Either a previously solid area starts shifting to the other party and the heretofore safe representative who had previously been fine with towing the party line suddenly finds himself needing to chase after the voters or gets elected from the outset in the other guy's terrain and thus end up diverging from the party average

Because of the geographically realignments that occurred in the 20th century, there were large numbers of these. Frankly, the concept is over used and over simplified because it fails to account for why and how they became Republican/Democrat and what factors drive their voting patterns and its diverging from the party average.

Vote View and DW Nominate are good measures of this and while they do tend to emphasize economic over other concerns, in the long run that tends to work out since the longest running divide has been business interests versus the poor (be they farmers or urban labor) and virtually everything else that has changed around that has been an evolution for the sake of promoting one side or the other of that divide. The Southern Strategy, was to mitigate the growing strength of the New Deal Coalition in the North. The realignment of big government versus small, was to match the realignment of interests for those core constituencies. The urban-rural divide, is the result of the move to the cities and the reduction of rural areas to just conservative leaning voters (or people spooked into voting such a way by demographic tensions such as those caused by migrant labor or African-Americans).

Divergence from the party mean has always been the result of hangers on after one of these transitions and the resulting delay caused by incumbency, money and relationships with existing power structures. In a sense that means that the default is to trend towards polarization as long as conditions remain static such as to avoid one of these changes. Fast growing states though are ripe for this, such as what you are seeing in Georgia but the conditions in Georgia don't lend itself to this phenomenon thus meaning that there were will be a quicker transition from one side to the other. This is for the most part what happened in Virginia as well.

It's kind of hard to be an "INO" president, since the president is generally very important in defining what the party stands for. The one president who really stands out to me is Carter, who had relatively little influence in Congress, was a bit to the right of the national Democratic Party, and who came reasonably close to losing re-nomination.

Going back further in history, Zachary Taylor and William Henry Harrison were WINOs, and Rutherford B. Hayes was a bit of a RINO.

John Tyler was even more so, and ironically the most Whig of all of them (Fillmore), ended up being seen as a traitor to a large segment of the party and helped to bring about its collapse. He also destroyed the American Know-Nothing Party, by splitting it on regional lines and driving its Northern wing into the Republican Party.

How so with regards to Hayes?
