While she chose the same format -- a pre-recorded video -- to announce the start of her campaign today just as she did in Jan. 2007, her message has changed.
Here's a look at the differences between Clinton's announcement pitch in 2007:
The Last Administration
What She Said Today: "Americans have fought their way back from tough economic times, but the deck is still stacked in favor of those at the top."
As a Democrat hoping to succeed a member of her own party in the Oval Office, Clinton will be playing more defense than offense when it comes to her predecessor's record. But history is not on her side: The White House has stayed in the same party after a two-term president only once since 1951 -- the year term limits were established for the office.
What She Said in 2007: "Let's talk about how to bring the right end to the war in Iraq and restore respect for America around the world."
What She Said Today: Nothing
Clinton ran on ending the Iraq War and ended up losing the Democratic primary to Barack Obama, who pummeled then-Sen. Clinton for her initial support for it. In 2015, with America again leading a coalition in the Middle East -- this time, against ISIS -- former Secretary of State Clinton will likely run on a more hawkish line, even if her initial campaign rollout remains focused on domestic policy.
What She Said in 2007: "So let's talk. Let's chat. Let's start a dialogue about your ideas and mine… With a little help from modern technology, I'll be holding live online video chats this week, starting Monday."
What She Said Today: "So I'm hitting the road to earn your vote. Because it's your time, and I'm hoping you'll join me on this journey."
In the proto-social era of 2007, reaching voters over "online video chats" was a new concept. Now, with the 24/7 news cycle and social media, Clinton 2.0 is reverting to face-to-face retail politics: In her upcoming tour of the early voting states, she's expected to hold small, intimate meetings with voters to introduce her candidacy, before the official campaign kickoff in May.
What She Said in 2007: "Let's talk about … how to end the deficits that threaten Social Security and Medicare. And let's definitely talk about how every American can have quality affordable health care."
What She Said Today: "Everyday Americans need a champion -- and I want to be that champion. So you can do more than just get by. You can get ahead -- and stay ahead."
Some things never change. Despite the implementation of Obamacare, the debate over healthcare continues. And both parties are still debating strategies to overhaul the country's entitlement programs for future generations. The economy took center stage in the 2008 general election with the recession, and Clinton plans to be a "champion" for middle class Americans.
What She Did in 2007: Clinton filmed alone on her couch in her Washington, D.C., home.
What She Did Today: Clinton appeared in the last 45 seconds of her two-minute-plus campaign announcement video, after a diverse mix of Americans described their economic situations.
While Clinton took center stage in her 2007 video, she could be considered a featured player in the new announcement, secondary to the other speakers, their stories, and the video's economic message.
