Missouri — Even as the official Republican Party continues to try to derail Missouri Senate candidate Todd Akin over his remarks about "legitimate rape," a powerful force within the GOP has begun rallying to the candidate's side: the party's socially conservative base.
Powerful Christian activists in the GOP have begun pushing back against party leadership, alleging it has gone too far in trying to thwart Akin and it is attempting to sideline issues that social conservatives care about, such as abortion.
The criticism is creating major tensions between the mainstream Republican Party and a key part of its base days before the GOP's convention is set to open in Tampa, Florida.
"Following the pounding of Todd Akin by the GOP kings and lieutenants in the last 36 hours, I've come to the conclusion that the real issue is the soul of America," wrote David Lane, an evangelical activist who's influential in the Republican Party, in an e-mail to fellow activists Thursday morning.
"The swift knee-jerk reaction to throw Akin, a strong conservative pro-life, pro-family born again Christian under the bus by some in the Republican Party is shining the light on their actual agenda," Lane continued.
"We haven't seen anything this vicious since some of the same operatives did this to (Sarah) Palin."
While many conservative Christian groups have criticized Akin over his "legitimate rape" comment and for claiming that women's bodies can prevent contraception in such cases, the groups have also emphasized that they stand with Akin in opposing abortion, even in instances of rape.
Many Republican leaders, from presumptive presidential nominee Mitt Romney to Republican National Committee Chairman Reince Priebus, have called for Akin to drop out of the race.
The National Republican Senatorial Committee and the American Crossroads super PAC that backs GOP candidates both announced that they will stop spending money on the Missouri Senate race. Even tea party groups that have backed Akin in the past said he should step aside for the good of the party and the conservative cause.
The Republican National Committee did not immediately respond to a request for comment on the social conservative criticisms of the party on Thursday.
Akin, who won a tough primary battle this month, has apologized for his comments but also defied pressure to get out of the election.
Republican officials have told CNN on condition of not being identified that the Akin controversy hurts on several fronts. It decreases the chances of capturing Missouri's Senate seat, which is crucial to GOP hopes of winning control of the chamber, they said.
And the brouhaha shifts the national discussion to divisive social issues that could repel swing voters rather than economic ones that could attract them in a climate of high unemployment and stumbling recovery, the GOP officials said.
Akin has bowed to Republican pressure to skip the Republican convention next week. But the Senate candidate was in Tampa on Wednesday night to meet with a powerful group of religious conservatives, according to a source familiar with the trip.
In a note to supporters Wednesday night, conservative Family Research Council President Tony Perkins heaped criticism on the GOP for abandoning Akin.
"Todd Akin has a long and distinguished record of defending women, children, and families -- and unlike the GOP establishment, I refuse to throw him under the bus over one inarticulate comment for which he has apologized," wrote Perkins, who is in Tampa attending events leading up the convention.
"As for the GOP, it has no rational basis for deserting Akin when it has stood by moderate Republicans who've done worse," Perkins continued. "Singling out Todd suggests a double standard, designed to drive out social conservatives."
