Other than silly "sign up for my brigage" logo (people might think he's a Buchanan-style candidate) The only problem I can see is he doesn't list his stance on abortion on his website. Considering New Hampshire is a conservative state (Benson clearly tells people he's pro-2nd amendment on that site), I wonder why not. My only guess is that his pro-life credentials aren't that good.
If any NH Freepers can vouch for this guy as a strong pro-life candidate, then by all means he deserves the nomination. We're in desperate need to replace some 'RAT governorships in November with all the vunerable GOP governors (including my own state, where the 'RATs are actually trying to associate the corrupt RINO governor with the current nominee, even though their candidate is far closer to the current governor's cronies).
On the abortion issue, I don't think there is statewide support to repeal Roe v. Wade. This is New England and not Alabama. Benson is a conservative Republican-- he broadcasts that exact phrase in his ads.
Just not a big issue up here, IMO.
