Every candidate can’t give civics lessons as part of their campaign. Every candidate can’t provide answers to every individual question every individual voter in their district or state might have.
And honestly, at this point, when the differences are more stark than they have ever been in any of our lifetimes it shouldn’t be so difficult to make that case.
People who say they don’t see the difference between Democrats and Republicans don’t want to. It’s a lie and a copout.
