Like the former President--that's the spelling that will make the most sense to the most people in the long run. I wouldn't recommend other "creative" spellings, unless you're okay with always having to spell it for people or having your baby girl spell it for people when she's grown.
Re: How Would You Pronounce...
I agree. Or Raygan or Raigen - people can say raisin right?
I think you if you want it pronounced Ray-gan then you should spell it Reagan. It looks much better than way too.
i agree
I was thinking more like "Rae-gan"
Not GIN.
