GWs top political student groups announced on Monday that two big-name speakers will visit campus: a third-party presidential hopeful and the man who propelled President Barack Obama’s re-election campaign.

Three-time presidential candidate and libertarian powerhouse Ron Paul will speak March 4 at 7 p.m. The former Texas Republican retired from the House of Representatives this year after 30 years.

Jim Messina, Obama’s campaign manager and top adviser, will speak Feb. 20 at 6:30 p.m. in front of about 300 people. Admission is free for the hour-long talk. The venue has yet to be determined, Chase Hardin, the communications director for the College Democrats, said.

Chairwoman of the College Republicans Sinead Casey said Paul would comment on the future of the Republican party.

“I am proud that our organization is bringing such an iconic figure for American democracy, whose following extends beyond party lines,” Casey said.

The College Republicans will give priority seating to dues-paying members of the group with a selection of free tickets available for non-members, which can be purchased on their website. Tickets will free for members of the GW community and $10 for the general public.
