But maybe Dems could possibly challenge Republican claims head on, possibly claiming that the Reps are using legislative fiat to inflict their beliefs on the country. That might be a very dangerous strategy, however. It would have to be framed very carefully recognizing that it could derail the campaign.
Republicans may be playing rope-a-dope. In that case, ignoring it is the only strategy.
