Des Moines, Iowa (CNN) - Prominent Iowa faith leader Bob Vander Plaats asked Michele Bachmann to dramatically alter her White House plans, according to the Bachmann campaign, including the possibility of dropping her presidential bid altogether.
"[Bob] Vander Plaats called us on Saturday and asked us to consider the possibility of merging with another candidate," Bachmann spokeswoman Alice Stewart told CNN. "He did not say whether we should be president or vice presidential candidate."
"And obviously, we didn't even consider that," Stewart added. "We said, 'Why would we do that?' "
Bachmann told CNN's "American Morning" anchor Ali Velshi on Wednesday there was no reason for the campaign to consider Vander Plaats' request for her to drop out of the race because "we've always polled above Rick Santorum." Santorum received a personal endorsement from Vander Plaats on Tuesday after the organization he heads, Family Leader, couldn't agree on who to endorse.
"I'm the one that has the momentum that's shooting up the chart right now," Bachmann said, crediting her performance in the last presidential debate for increased attention to her candidacy.
Family Leader is a Christian organization that holds sway over many Iowa social conservatives - a crucial voting bloc in the state's January 3 caucus. But Bachmann boasted, "I have probably the strongest level of support of the candidates here (in Iowa) among evangelical supporters," and cited her endorsement from 100 pastors and conservative TV host Glenn Beck.
CNN was unable to immediately reach Vander Plaats. A spokeswoman for The Family Leader refused to comment.
Earlier Tuesday, Vander Plaats and Family Leader Vice President Chuck Hurley endorsed GOP candidate Rick Santorum. In praising the former Pennsylvania senator, they essentially urged other Republican presidential hopefuls to end their campaigns and coalesce around one candidate.
The Family Leader refused to issue an endorsement as an organization, as its board members could not reach consensus on who to support. The group's seven-member board had recently narrowed its options down to Bachmann, Santorum, Texas Gov. Rick Perry and former House Speaker Newt Gingrich.
The goal for The Family Leader and other like-minded social conservatives is to avoid splitting the evangelical vote by coalescing around one conservative candidate who could stop Mitt Romney from winning the Republican nomination. Many social conservatives and other religious leaders in the state have openly labeled the former Massachusetts governor a "flip-flopper," a criticism the campaign frequently beats back, while others have seen Romney's Mormon faith as an issue.
Representatives for leading social conservatives in the state held a secret meeting in November as part of the effort to deny Romney the GOP nomination.
Vander Plaats has criticized Romney's scant campaigning in the state compared to the other GOP contenders.
At the Tuesday announcement of their support for Santorum, Vander Plaats said, "If the Des Moines Register wants to endorse a candidate who's barely been here, then I think it's okay for us - Chuck and I - to endorse a candidate who's has been to about 350 communities in the state of Iowa."
The Register, the state's largest newspaper, on Sunday endorsed Romney's candidacy.
