Mercadia,
It may be strange, but it is certainly not new. I'm not sure that the average voter takes the time to measure the candidates. In general, I think the vast majority of voters make their decsions based on their party affiliation, particularly dems and repubs ( I think independents may do a little more research than most as they can choose a dem, republican or 3rd party candidate). The next thing voters think about is what their party candidates can do for them, without thought to feasibility. For instance, a lot of people voted in the last two elections based on Bush's stance on abortion and gay rights--without really thinking about the fact that the president doesn't make any laws (executive orders not withstanding). People also thought that Bush was a conservative---but one certainly can't tell based on our deficit.
In terms of endorsement, no candidate really vets all of their endorsers or gives them talking points. What they want is that endorser, particulary state politicians, to utilize their base, to get votes. So again, the fact that this particular endorser was not able to answer the question may be dissappointing, but is certainly not surprising.
