NRA score is A
What did he do to downgrade it from A+?
What the Grades Mean:
The NRA-PVF is non-partisan in issuing its candidate grades and endorsements. We do not base our decisions on a candidate’s party affiliation, but rather on his or her record on Second Amendment issues. The NRA is a single issue organization. The only issues on which we evaluate candidates seeking elected office are gun-related issues.
A+ A legislator with not only an excellent voting record on all critical NRA issues, but who has also made a vigorous effort to promote and defend the Second Amendment.
A Solidly pro-gun candidate. A candidate who has supported NRA positions on key votes in elective office or a candidate with a demonstrated record of support on Second Amendment issues.
AQ A pro-gun candidate whose rating is based solely on the candidate’s responses to the NRA-PVF Candidate Questionnaire and who does not have a voting record on Second Amendment issues.
B A generally pro-gun candidate. However, a “B” candidate may have opposed some pro-gun reform or supported some restrictive legislation in the past.
C Not necessarily a passing grade. A candidate with a mixed record or positions on gun related issues, who may oppose some pro-gun positions or support some restrictive legislation.
D An anti-gun candidate who usually supports restrictive gun control legislation and opposes pro-gun reforms. Regardless of public statements, can usually be counted on to vote wrong on key issues.
F True enemy of gun owners’ rights. A consistent anti-gun candidate who always opposes gun owners’ rights and/or actively leads anti-gun legislative efforts, or sponsors anti-gun legislation.
? Refused to answer the NRA-PVF Candidate Questionnaire, often an indication of indifference, if not outright hostility, to gun owners’ and sportsmen’s rights.
