However, in the heat of a campaign in which Trump has pulled even is not the time to address it."
This issue won't make or break Trump's election as Trump has taken it off the table for the debates. The big media might try to bring it up again, but most voters still on the fence at this time will see it as desperation on the part of the media and the (D)'s, especially in light of the fact that it was the (D)'s who initiated the questions (not to mention, the first eligibility lawsuit). This issue, as a political weapon, is now ineffective for the D's.
As fo those interested in seeing the truth known, we can always walk and chew gum.
Anybody who thinks "Birther" is a racist term, the only reason the MSM would use it, would never vote for Trump anyway, so you are correct, non-issue.
