On a visit to Indiana I meet Darlene Boatman, a Republican supporter of President Bush. This time, Darlene is going with Hillary.
She has made the necessary arrangments to be able to vote in the Democratic primary. But this is not part of Rush Limbaugh's Operation Chaos.
Far from it - Darlene is smitten.
She had given up on America, she tells me, to the extent of trying to persuade her adult sons to emigrate.
But "this little woman" with her guts and determination and sheer bloody-minded refusal to die, this woman has re-established Darlene's faith in the nation.
I wonder how many similar people there are who have been looking at the Clinton phenomenon and just thinking, "wow!"
And thinking that "thinking wow" is enough.
Back with the Democrats, a day spent among Hillary supporters in Indiana convinces me of one thing: her fire is not yet extinguished.
Oddly, what I found convincing - for instance at a packed fire-house meeting in Merrillville (America's fastest growing town the locals tell me, though it would have burned to the ground had there been an emergency today) - was the reasonableness of her people.
The candidate herself can seem mighty scary. The Obama charge that "she will do anything to win" is not without some justification.
Yet the mood among her most enthusiastic backers is still positive. I could find not a single real Obama hater, no-one who wouldn't vote for him in November - there was not a racist among them. Just a real enthusiasm for her guts and a belief that this is not over.
They all think she can win the popular vote, though as we know, they have invented their own arithmetic for the purpose ...
