She is different than her husband. He always crossed party lines...all through his presidency. If this was NOT decided before his death...then I too think she'll stick to that decision, after thinking about it. She was extremely protective of the love of her life.
I think, although we all remember the Reagans fondly, that, perhaps, we forget a bit since they've been out of the limelight for a while. The one, overall factor in their decisions -- ALWAYS -- "what's the right thing to do?"
My favorite political cartoon was from way back. I believe it was the '83 budget, but I could be wrong. The cartoon showed a picture of Reagan holding the budget book, with a stern and determined face. From his waist down, he was an old oak tree trunk.
Don't worry, if this was decided before OR after Reagan's death, she won't back down. She's not THAT different from her husband.
