Trump vowed to go all-out in the final three weeks so he’ll have no regrets — even if he loses. The nominees retrenched behind familiar arguments a day after appearing together at a charity event that veered into cutting personal attacks, an unexpected metaphor for this year’s take-no-prisoners presidential campaign.
