Washington (CNN) - Just as support starts piling up for a second Hillary Clinton presidential campaign, the opposition forces are marshaling their resources to keep up.
Pro-Republican Super PAC America Rising is launching a fundraising effort today as their answer to the growing tide of support for Clinton. The PAC has a brand new site, StopHillary2016.org, a one-stop shop for Clinton haters.
And they're blasting a series of e-mails to randomized groups of donors to solicit money for the cause.
One draws on the lessons learned by Mitt Romney's failed presidential campaign. The PAC's chairman, Matt Rhoades, had managed the Romney campaign in 2012. He writes in the new fundraising note, "President Obama started his reelection campaign on his first day in office. I saw firsthand how big of an advantage that four year head start gave him in 2012."
He goes on, "We can't allow that competitive advantage [to] occur again."
The second begins by saying it's no secret Clinton is preparing another bid and explains the organization "was formed to prevent Americans from ever having to see another Clinton in the White House or suffer through 12 years of Democrat rule."
It continues, "Whether it's Hillary, Joe Biden, or liberal up-and-comers like Elizabeth Warren, we need to stop these Democrats in their tracks now." And it reminds that the "Clinton Machine" is so powerful, Republicans need to start collecting research on the former secretary of state to "define the real Hillary before another Clinton Administration damages our country."
A third e-mail stokes fears of another Clinton in the White House by ticking through a series of Clinton scandals, including her leadership of the State Department during the attack on the U.S. mission in Benghazi.
In addition to bringing in funds to do research and finance TV ads when the campaign gets closer, part of the exercise is designed to determine which of these messages sticks best by seeing which e-mail solicitation brings in the most money, according to the PAC.
