I don't judge people on whether they are undecided or not or whether they take a long time to decide (some are just indecisive in nature and like to mull things about). Everyone is different and en led to their opinion - it's supposed to be a free country, after all. They can be as political or Apolitical as they want. Seems like it's hard for you to think that some could possibly not know or care what's going on politically but some people just, you know, live their lives. - I too was such a person - too busy with my life to care much.
I make no apologies for Trump but it's not like everyone doesn't know exactly what he thinks from what he says and tweets. To me, that's preferable to some smooth, charming, presidential (but also) liar who promises that I'll get back $2500 and keep my doctor and my health plan. IMO, people (especially women) are so concerned about his behavior - what exactly does his behavior DO to you personally - maybe hurt your feelings, maybe you don't feel proud of your president on the international stage, maybe you wince at the language. Instead, those policies are what directly affects you - do you want to continue paying under $2 per gallon for gas, enjoy looking at your 401k balance, enjoy that bigger paycheck? - those are the things that affect you and yours - just put him on mute - ignore what he says and enjoy the results of what he does.
