The super PAC looking to build support for a potential Hillary Clinton presidential campaign raised over $4 million in 2013, the group announced Tuesday.
According to the super PAC, 98 percent of those donations were contributions of $100 or less. It raised $2.75 million in the second half of the year, over double its fundraising haul for 2013's first six months.
"Thanks to the groundswell of enthusiasm for Hillary's potential run and the steadfast commitment of our supporters, we have exceeded our goals and are ahead of schedule in raising the funds necessary to build a grassroots army that can be activated the moment Hillary makes a decision," Ready for Hillary executive director Adam Parkhomenko said in a statement.
As speculation grows over whether or not Clinton will run in 2016, the super PAC has ramped up its grassroots efforts.
Earlier Tuesday, it announced that it was hiring additional staff members to help with fundraising and outreach. And earlier this week, Time reported that the group had rented Clinton's email list from her 2008 campaign in an effort to "connect with her past supporters."
