Who's in line next for presidential campaign announcements?

The staff of The World and Everything in It has profiled 22 possible 2016 presidential candidates in its “White House Wednesday” series. Now they take a look at who’s ahead and who’s making moves as the big campaign gets closer.

Let the games begin. For the last several months, candidates have been battling one another behind the scenes in what’s known as the invisible primaries, looking to win commitments from top donors, staffers, and strategists. But with candidates formally announcing their campaigns, the race for the Oval Office is about officiallyto begin. Sen. Ted Cruz, R-Texas, was first to announce his candidacy last week, and several others won’t be far behind. Sen Rand Paul, R-Ky., is expected to announce Tuesday in Louisville. From there, he’ll hit the road for a five-day, five-state announcement tour including stops in New Hampshire, South Carolina, and Iowa. The following week, Sen. Marco Rubio, R-Fla., will announce his presidential plans. Rubio has reportedly reserved the iconic Freedom Tower in downtown Miami for the event. And former Hewlett Packard CEO Carly Fiorina is sounding more and more like a candidate. She told Fox News Sunday host Chris Wallace that the odds of her running for president are higher than 90 percent. She said she would announce in late April or early May.

Opponent rising. A possible rival of Hillary Clinton’s for the Democratic presidential nomination took the frontrunner to task this week over her email scandal. Former Maryland Gov. Martin O’Malley, told ABC This Week that Clinton is not the right leader for the times. “The presidency of the United States is not some crown to be passed between two families. It is an awesome and sacred trust to be earned,” O’Malley said. The question is, if things do continue to go in the wrong direction for Hillary, would Democrats choose O’Malley as their backup plan? Right now he’s the only other guy, ostensibly, in the Democratic field. But if things keep going south for Clinton and the party starts smelling blood in the water, other fins could start swirling around Clinton.

Presidential power rankings. The presidential power rankings are a weekly snapshot of where the race for GOP presidential nominee stands right now. Polling is the main factor in the changes in the rankings from one week to the next. This week incorporates new polls from New Hampshire, Nevada, and South Carolina.
