As a former Delawarean I can tell you that the majority of Republican politicians and most voters in Delaware are RINO’s. Pete DuPont, RINO that he may be, is a well respected person with both Delaware Republicans and a good number of independents.
O’Donnell already has the Conservative vote, so there is no need to reach out to them. What Pete DuPont has done is call on the RINOs and Independents in Delaware, and formal endorsement or not, his article can do more good than bad.
I voted for Pete DuPont when he was running for President!
