Should Hillary Clinton go ahead and launch her 2016 presidential campaign? Her advisors appear to be split on the issue.

By this time back in 2008, Clinton was firmly in the race, posting a YouTube video on January 21, 2007, stating that she was “in it to win it.” But although Clinton remains the prohibitive favorite to win the Democratic nomination for president and seems a certainty to run, aides are contemplating whether she should delay her entry into the race by a few months, according to a CNN report.

The battle for the Republican nomination has already begun in earnest, with a host of candidates vying for the GOP nod. Mitt Romney, one of the front-runners, recently dropped out just weeks into a prospective campaign. Meanwhile, two current governors, a former governor, and three senators are all actively involved in the race on the Republican side, and CNN suggests that up to 10 or more Republican candidates could be battling it out by the summer.

It may not be until then when Clinton finally declares her own candidacy. The campaign is considering this possibility so that it happens right at the start of the third fundraising quarter, which is gaining popularity in her circle versus an April announcement.

Right now, the likelihood of her doing so appears to be 50-50, CNN reported, quoting anonymous sources.

With the race for the Republican nomination heating up, some in Clinton’s camp are worrying that the GOP could come after her and she wouldn’t have the campaign in place to respond to those attacks. So far, Democrats have been relying on a superPAC known as American Bridge, but a real campaign will be needed to more fully respond to attacks.

Still others believe the fierce Republican competition could work in Clinton’s favor by causing them to take aim at each other instead of Clinton since she isn’t yet in the race.
