Ok, I agree with you, but have you also considered that
He (Hoffman) was a truly awful selection. I hope this fiasco has sent a message to the Conservatives, that you can't just run any inarticulate boob who espouses the "right" values.
I've got a novel idea. Why don't we hold an election to see who the Republicans in the district want? We could call it something like . . . a primary, because it comes before the general election. Wow, why didn't anyone think of that???
Hoffman had no political experience or expertise, no organization and no charisma whatsoever. He had no backing from local politicians. He did not live in the district. He was attacked constantly by the two major Parties and outspent over 10 to one. The Union activists and others poured enormous resources into the race. He was opposed by all major media and called an extremist and fringe candidate.
Still he came within 2 points of winning the election and would have won had not Scozzafava and her friends endorsed the Democrat and made phone calls for him in the last week of the campaign. If Hoffman had a fraction of the resources that the Republicans gave to Scozzafava he would have won in a landslide.
The lesson is that principles are far more important than political experience or endorsements and if it had not been for the total incompetence of the Republican Party a conservative would have won.
