Ask him this question, "Name one thing the republican paRTy ever did for the benefit of the common working man/woman." If he asks what then Democrats ever did, tell him this.
1 Social security under FDR. the repubs fought it tooth and nail.
2 Minimum wage
3 women's right to vote (Woodrow Wilson)
4 the right to collective bargaining
5 Medicare
6 Overtime
7 Safer working conditions (John L. Lewis)
To name a few. of course, if the moron is rich, he will say every one of these things is bad for business.
