Hold onto your seats everyone, things are about to get interesting.

Rumblings of a Joe Biden presidential run continue to get louder and despite the claims of James Carville, some Democrats and the Clinton campaign are starting to panic.

Just days ago, Hillary Clinton cut her vacation short in order to get back onto the campaign trail. Her return came shortly after Massachusetts Senator Elizabeth Warren, a darling of the left who many wish were running for president instead of Hillary, met with Biden in Washington D.C. for lunch. Warren's non-commitment to another Senate run is also making the Clinton camp extremely nervous because it's an indication Biden may choose Warren as his VP nominee.

But it appears Hillary Clinton isn't the only part of the Clinton equation upset about a possible (and probable) Biden run. Former President Bill Clinton seems to be concerned a Biden run could destroy his chances of reoccupying the White House. From POLITICO:

Clinton’s camp, hands full with the email controversy and a surprisingly stout challenge from independent Vermont Sen. Bernie Sanders, isn’t in a patient mood. Bill Clinton, according to a person who has spoken with the former president in the past couple of weeks, is “very agitated” by the possibility of a Biden candidacy and incensed at the press hype around a possible bid.



If Biden does in fact get into the race, there's no doubt President Obama will not only endorse him over Hillary, but will offer the resources and infrastructure that got him elected in 2008 and 2012 as additional support.

The longtime feud between the Obamas and Clintons is far from over.
