The president of the Family Research Council, a top religious political group, said Thursday night that conservative activists should withhold their political donations to Republicans until the party decides where it will stand on social issues.
"Until the RNC and the other national Republican organizations grow a backbone and start defending core principles, don’t send them a dime of your hard-earned money," Perkins said in the email, a copy of which was obtained by CNN.
"If you want to invest in the political process, and I encourage you to do so, give directly to candidates who reflect your values and organizations you trust — like FRC Action."
Perkins says that the RNC proposal will only drive away young voters who do not support same-sex marriage.
"Instead of trying to appease millennials, Republicans should try educating them on why marriage matters," Perkins wrote. "There’s an entire group of 'Countercultural Warriors' full of compelling young leaders who are all going to the mat to protect marriage."
In a CBS News poll released late last month, 49 percent — a plurality — of Republicans under 30 years old say they support same-sex marriage, while 46 percent do not believe gay couples should be allowed to wed. Overall, 73 percent of Americans under 30 back gay marriage.
Still, Perkins says Republicans must "pass a resolution reiterating the GOP’s support for the party platform that was overwhelmingly adopted in Tampa last year."
That platform included provisions saying the party would oppose same-sex marriage. Members of the Republican National Committee were meeting Friday in California, and are expected to take up a resolution reaffirming that position.
