Campus political groups to register students to vote tomorrow.

Columbia University campus Republicans and Democrats will unite for one cause tomorrow afternoon: voter registration. The Columbia Political Union, an organization that aims to increase student involvement in the political process, will assist in signing up voters.

From 4 to 6 p.m. College Republicans will be tabling on College Walk and encouraging people to write letters to the troops in Iraq, said Lauren Salz, executive director of Columbia College Republicans, over e-mail.
