I've never been a party chair but I've spent a lot of time in other organizations. Points to consider:

1) You'll probably spend a lot of time listening to some of the people gripe about some of the others. Much of this time will be spent listening to a rehash of the same gripe you patiently sat through last month... and the month before that. Also, some of these gripes will be pointless recriminations, about what should have been done (now that it's too late to do it that way), who's at fault, and, for that matter, who did what dastardly thing to whom five years ago.

In some organizations, especially those that attract opinionated people, being the "leader" is like being the only fire hydrant on a block with 50 dogs.

2) Just because you're the leader, don't expect a whole lot of deference. You may come to feel, even if only subconsciously, that because you're putting in so much time and effort for the good of the organization, people should do things they way you want. They won't, at least not always.

3) Don't be the volunteer of last resort. "Task X ought to be done, no one has volunteered to do it, Blue is the chair, therefore it's her responsibility" -- this is BAD. Your only obligation is to make reasonable efforts to find someone to do it. If you can't, then it doesn't get done. Otherwise you'll burn yourself out.

If you believe in the goals of the organization, taking on a leadership role can give you a chance to do a lot to further those goals. It can also be a royal PITA. If you're prepared to deal with the personal costs -- the time commitment, the abuse, the other PITA parts -- then do it. And good luck!

ETA: I see your concern in the OP is "Will Blue as party chair be good for District 19." I was confident that it would be; my question was "Will Blue as party chair be good for Blue?" Pardon me if I sounded too negative, but if you take the position, you should do so with eyes wide open.

I also forgot one very important item in the list:

4) Never expect gratitude.
