For years Delaware politics was all about Mike Castle, Tom Carper, William Roth, and Joe Biden.
Delaware has one House seat.
Carper (D) was in the House 83-93, Governor 93-01, Senator 01-present.
Castle (R) was governor 85-92, House 93-11. He and Carper arranged a swap due to term limits in 1993 to avoid running against each other. Note their parties and they still worked that out together.
Roth (R) was in the House from 67-70, Senate from 71-2001.
Biden (D) was in the Senate from 73-09.
So from 1970 to 2010, out of 160 man-years for House, Senate, and Governor, those four controlled 118 of them or something like that. There was a 16 year stretch where those four held all four major positions.
The only time any of the four ran against each other was when Carper ran against Roth for the Senate seat in 2000. Roth was 79, but Castle refused to primary him. Carper made the race about age, Roth collapsed twice during the campaign, and Carper won 56-44.
Castle would have taken Biden’s seat when he became VP, but he lost the GOP primary to the crazy witch lady and Coons beat her. Castle beat Coons in polling by 20+ points.
Castle was moderate, in favor of campaign finance reform, and would be at the left end of the current GOP. Roth was all about tax cuts, incentivizing saving and investing (yes, that Roth), and cutting spending. Romney-esque.
Carper, Biden, and Coons for that matter are all standard fare corporate Dems.
