The low-key announcement is because Clinton wants an uncomplicated start to the long campaign ahead and already having huge name and recognition.
Clinton is former secretary of state and wife of former President Bill Clinton.
Clinton will travel to the key early voting states of Lowa and New Hampshire after the announcement.
“She’s expected to make her intention to run known on Sunday,” the source said.
Clinton is expected to participate in small events to interact with the voters and hear their concern and to explain why she wants to be president.
Clinton’s campaign is different from other candidates for presidency who held big events to announce their campaign.
Steve Elmendorf, Democratic strategists said a more modest rollout will be helpful for Clinton, who lost the 2008 Democratic presidential race.
He said, “She hasn’t been out campaigning for a long time, you need to get your sea legs back. All candidates benefit from listening to people and getting a sense of what concerns voters have and respond to them. It’s a long campaign. There’s no need to start out with a bunch of big rallies.”
Social media tactic is used by Obama in 2008 and Clinton is likely adopting the same tactic.
On Friday, Clinton release an update on “Hard Choices” in which she described about her felling of her first grandchild and her final days as secretary of state.
