Bush, the son and brother of former presidents, is emerging as a Republican establishment favorite, although many conservatives are skeptical.
The former Florida governor says in a video posted today on Facebook that the "Right to Rise PAC" will allow him to "support candidates who believe in conservative principles to allow all Americans to rise up."
An aide says the organization also allows Bush to hire staff, conduct polling and pay for travel as he courts key donors and Republican officials.
Several potential Republican presidential candidates have already formed similar committees.
