Former Florida Gov. Jeb Bush has decided to “actively explore” a presidential bid after conversations with his family over Thanksgiving, he said in a Facebook post Tuesday. While Bush had been making steps toward a presidential bid with recent speeches in early primary states and plans to release documents from his time period as governor, the timing of Tuesday’s announcement was widely unexpected and will quicken the pace for some would-be Republican primary challengers. In the post, Bush writes that over the holiday he “talked about the future of the nation” with his family. “As a result of these conversations and thoughtful consideration of the kind of strong leadership I think America needs, I have decided to actively explore the possibility of running for President of the United States,” he said. Bush has been moving toward a run for months and in recent days sparked renewed speculation over his plans with a visit to the all-important early primary state of South Carolina to give a commencement speech Monday, and his comments in a Sunday interview that he felt he “would be a good president.” RELATED: Bush to grads: ‘Shake things up’ Democrats scoffed at his announcement. Democratic National Committee spokesman Mo Elleithee suggested it was simply meant to draw press, but dismissed the possibility of a Bush run either way. “I don’t know what the difference is between ‘thinking about’ running and ‘actively exploring’ running, but I suspect it has a lot to do with keeping his name in the news,” Elleithee said. “However you see it, there’s no parsing this simple fact: Jeb Bush has fully embraced the failed economic agenda that benefits only a select few at the expense of the middle class. That’s not going to change no matter how many different ways he says he may run.” Bush’s announcement is sure to speed up the timeline for many other potential Republican presidential contenders on whether to jump in as well. Bush is seen as a top pick for establishment Republicans hoping to encourage the party to nominate a candidate they see as most electable on the national stage. Many observers believe if Bush jumps in the race, Florida Sen. Marco Rubio — who’s been mentored by Bush since his entry into Florida politics — wouldn’t run. And he’d likely make it tougher for some of the more establishment-minded governors, like Texas Gov. Rick Perry or New Jersey Gov. Chris Christie, to find footing in the race. However, a source near Rubio said Tuesday that while Bush’s announcement changes the dynamic of the race, the junior Florida Senator is still “on track to run for president” in 2016. And Kentucky Sen. Rand Paul, who has been actively preparing for a bid and would likely run to Bush’s right flank, also seemed nonplussed by the announcement. “I think we’re a big tent – we can use moderates, conservatives, libertarians — we need em all,” he told reporters walking into the Capitol. Asked whether he could win the nomination, Paul demurred. “I think the more the merrier – the public will determine that.” Bush added in Tuesday’s post that he hopes “to visit with many of you and have a conversation about restoring the promise of America” in the coming months.

If he does make his bid official, he’ll likely face fierce opposition from conservatives in the primary, who have long been frustrated with his advocacy for Common Core educational standards and his support for a more moderate vision of immigration reform. RELATED: Bush releases 250,000 emails He’s previously expressed support for a pathway to citizenship for undocumented immigrants, though he’s wavered in that support since. And while he’s come out in opposition to President Barack Obama’s executive actions on immigration, he’s also urged Republicans to act on immigration reform “rather than have their heads explode.” That moderation on immigration reform — and his diverse family, as his wife was born in Mexico and he speaks fluent Spanish — have many in the GOP hopeful Bush could help the party overcome some of their deficit with Hispanic voters, which has proven to be problematic for them in national races. Despite the likely conservative opposition, Bush has hinted he wouldn’t shift to the far-right to please GOP primary voters if he runs. During the Wall Street Journal CEO Council annual meeting earlier this month, Bush warned that the GOP presidential nominee shouldn’t “lose the primary to win the general without violating your principles.” The comments came as the conservative and more centrist wings of the GOP continue to debate a path forward for the party, with many on the right arguing former GOP presidential nominee Mitt Romney lost in 2012 because he didn’t stand strong enough on conservative principles. But Romney and Bush, despite the conservative criticism, remain two of the most popular figures in the party, and indeed both led the recent McClatchy-Marist national poll of the potential GOP presidential field. Romney took 19 percent, while Bush came in second with 14 percent support; with Romney out of the race, Bush would lead with 16 percent support, followed by former Arkansas Gov. Mike Huckabee with 12 percent.
