You do NOT force them to denounce the platform, ever. Democrats lie. They will denounce it to the rafters to be elected and then tow the line with it when elected. Their platform needs to be shoved up their asses every day and when they try to denounce it we should be reminding the public of their lying history and call them liars in oublic every day. Anyone not comfortable doing that is with them.
When they denounce their platform ask them ‘But you’re running as a democrat. Are you no longer a democrat?’ Ask them ‘Are you refusing help from the national party? Are returning any financial support ?’
It’s not hard to be aggressive. It’s just hard for the over-advised ‘re-packaged by professional political DC Beltway advisors sent by the RNC who wants to just be liked by the press’ GOP candidate to do. !
