Will Republicans forget that Trump held 3 rallies without masks and social distancing?

Trump now announced that people should wear a mask and that wearing a mask is patriotic.

Will Republicans who wouldn’t wear a mask before start complying now? I know many Republicans were wearing masks already, but I’m talking about those who wouldn’t.

Will they say Trump always promoted masks?

How are Republicans going to rationalize it all?

Who are going to be the holdouts to still not wear masks?

Will this help Trump in the polls?
