The GOP controlled Texas House of Representatives has passed a bill requiring people to show photo identification before voting.

Republicans have been trying to pass voter ID legislation for several years, and Democrats have been fighting it ferociously.

GOP lawmakers say it's necessary to prevent voter fraud. Democrats say it's aimed at poor and minority voters who are less likely to have state-issued identification cards.

The Senate has already passed its own version of the Voter ID bill.  A conference committee will work out the differences and send the result back through both houses for a final vote.

At least eight states have strict photo ID requirements, according to a late 2010 study by the National Conference of State Legislatures.
