What week will Clinton announce?

[Mr. Morden]

She has paid speeches on her schedule as late as March 19th, so she's unlikely to announce before then.  In fact, if you read the "Tea Leaves" thread, you'd realize that the most likely option is April:

The week after Easter is being pegged as the likely launch window for Clinton 2016:

Right around the same time Obama did: the end of February, right around my birthday.

As explained upthread: She has paid speeches on her calendar as late as March 19, and all signs from her camp point to an April launch for her campaign.

[Mr. Morden]

If she wasn't running, she'd have said so by now. Just after Easter sounds about right.

She'd be putting her party at a huge disadvantage if in March or April she abruptly announced she wasn't running. The non-Hillary Democratic field is even more nebulous than the current Republican field and any Democrats would be behind the Republicans as far as lining up donors and staff and getting their ground operations up and running.

The GOP candidates are arranging donors and staff right now in order to set themselves up for the primaries, not the general election.  If the Democratic race were thrown wide open now (or in April) by Clinton dropping out, there'd be a mad scramble among Democratic candidates to get their campaigns together for their own primaries, but the fact that they'd be doing that later than the GOP candidates wouldn't have any impact on the party's prospects in the general election.
