I suspect that Elizabeth Dole’s endorsement of Mitt Romney might matter to someone, but I doubt it matters to many voters, and especially the independents and moderates it takes to win national elections. Dole lost Jesse Helm’s old Senate seat in a lopsided 53-44 loss to unheralded Kay Hagan in 2008 in a vote that was as much an expression of discontent with GOP Washington insiders as it was dissatisfaction with an ineffective “me too” Senator.
