Democratic voters are far more likely to be in support of anti-discrimination laws against LGBT individuals. A Gallup poll reports that 74% of Democrats are supportive of anti-discrimination legislation, compared to only 27% of Republicans. Likewise, the most recent Democratic platform expresses commitment to enacting protections for LGBT rights, while the Republican platform does not.
Anti-discrimination laws are designed to prevent discrimination against particular groups in matters of economic, social and cultural discrimination.
