The field of Republicans running for president is about to get a bit more crowded as New Jersey governor Chris Christie is expected to announce his bid to run on Tuesday.

Bloomberg reports:

Chris Christie Said to Plan Tuesday Announcement of Presidential Run

New Jersey Governor Chris Christie will join the crowded Republican 2016 field Tuesday, two people with knowledge of his plans said.

Christie, 52, will cap months of speculation with an announcement in his hometown of Livingston, said the people, who asked for anonymity because they weren’t authorized to speak before his speech.

While Christie previously said he hadn’t made up his mind, he’s spent months making policy speeches and holding meetings in key primary states including New Hampshire and Iowa. He’s traveled as “honorary chairman” of Leadership Matters for America, his political action committee.

Samantha Smith, a committee spokeswoman, didn’t immediately return a telephone call seeking comment.

According to a new report from FOX News, Christie is planning to embrace a specific strategy:

Christie to embrace underdog role as he launches 2016 bid

When New Jersey Gov. Chris Christie enters the race for president next week, he’ll do so as an underdog.

The launch of the Republican governor’s White House campaign is the culmination of years of groundwork that began even before his landslide re-election to a second term as governor in 2013, but one nearly felled by scandal and a descent from his standing as one of the nation’s most popular state leaders to a politician whose approval ratings have reached record lows.

It’s a reality Christie and his supporters are ready to embrace.

“Clearly, he’s got some uphill work to be done,” said Ken Langone, a co-founder of The Home Depot and one of Christie’s most vocal cheerleaders. “But I think it can be done.”

Of course, not everyone is convinced that will work.

Thomas Fitzgerald of the Philadelphia Inquirer:

Has Christie’s ship already sailed?

He had them at “sit down and shut up!”

In the summer of 2011, some Republican leaders and billionaire donors begged Gov. Christie to run for president to save the party. Less than thrilled with the available options, they loved his blunt style and success in a blue state. Christie wavered, but passed.

“Now is not my time,” he said.

As Christie prepares to announce his 2016 presidential intentions Tuesday, after months of travels to early-voting states, some question whether he missed his moment. The Republican electorate seems to have given a collective shrug and moved on; Christie is near the bottom of the polls.

“You need to go when it’s your time,” said Douglas Gross, a Des Moines lawyer and GOP power broker. “The luster wore off. They pass the pie, and you’d better take your piece, because it’s not coming around again. I don’t sense a clamor for Christie.”

Things can certainly change, but if Christie’s poll numbers continue to sag he won’t be included in the top tier debates. That alone could seriously harm his chances.
