Here's a glimpse at some of the stories the ABC News political team will be tracking in the week ahead:
1. Hello, Hillary
We're led to believe she'll be humbler, chastened, and different -- yet unbelievably heavily favored all the same.
The roll-out is expected to be a slow one, starting with social media and a video -- not that that's been tried before. Then will come early-state visits, with team Clinton rejecting big campaign rallies for smaller, intimate settings, at least in the early going.
2. Big Target
Hillary Clinton's entry into the race will open a new 2016 chapter that many will rush to write.
It will unleash the anti-Hillary forces, which have hardly been bashful to date in staking out strong stances against almost anything she's ever done. Before we even get to the Republicans, we start with the Democrats.
3. Marco's Mark
It's either great luck or terrible timing that has Sen. Marco Rubio getting his big moment on Monday at just about the same time Hillary Clinton dominates the news cycle.
Rubio has stronger foreign-policy credentials than many of his rivals and a position on immigration that will take some explaining to the GOP base.
4. Christie Comeback?
Forget bridges -- if that's possible for the moment. Will Chris Christie play on the road?
The Christie comeback would run through New Hampshire, where he'll arrive Tuesday for a few days of the kinds of town-hall meetings he's made famous back in New Jersey. Anything can happen in those settings, of course -- and what Christie is likely hoping is that he can answer questions about where he's been with a few strong exchanges with voters.
He's also hoping that long-expected (and long-delayed) possible indictments of former close associates don't interfere with his campaign messaging, with reports swirling that prosecutors are wrapping up their Bridgegate probe.
In any event, Christie needs to get back into the political conversation sooner rather than later.
5. Hot Spots
Two of President Obama's biggest foreign-policy gambits are coming to critical junctures as Congress returns from a two-week break.
On Iran, a key Senate committee is set to consider a bill that would give Congress an oversight role in any nuclear deal -- with the promise of more congressional involvement in the near future.
The president has arguably made more progress in his relationship with the Cubans and the Iranians than he has with Republicans in Congress. Those facts will be on display during this legacy-building phase of Obama's second term.
