MeridianTeaParty.com's message is now prominently displayed along Interstate 20/59 in Meridian.
The group has raised enough money to put up a billboard sign at the Bonita Lakes Mall exit.
The sign reads, "Help Take Our Country Back, One Politician at a Time", and lists the group's web address.
It has only been up a week, but group member Paul Tarver says reaction has been strong in terms of momentum and fundraising.
"We aren't going to get any feedback as for if we changed someone in Atlanta's mind about if they are going to vote or not," said Tarver. "But if we made them think about it between here and Birmingham, then we have accomplished what we needed to accomplish. "
In order to keep the sign up until November, the group still needs to raise more money.
A barbecue fundraiser called Patriots in the Plaza will be held July 2 at Dumont Plaza. Tickets will go on sale next week.
