House Armed Services Vote Bans Gay Marriage on Military Bases

Do Republicans every get it at all?"On the same day that President Obama threw the weight of the White House in support of gay marriage, defense lawmakers in the House banned the practice from taking place on U.S. military bases". If the poll show that 50% of American want to see people treated fairly I don't understand why Republican always go against the Americans people doing thing they want to do.  I feel very frustrated when these leader think our voice doesn't matter.
