In a seemingly symbolic move, 100 conservative Christian leaders agreed to unite behind the presumptive Republican presidential nominee John McCain at a meeting Tuesday in Denver, Colo., Time.com reports.

McCain may have become the default choice for some of those leaders, who expressed doubt about presumptive Democratic presidential nominee Barack Obama. One guest present at the meeting said the motivation behind uniting and offering collective support was closely tied to a desire to defeat Obama.

"None of these people want to meet their maker knowing that they didn't do everything they could to keep Barack Obama from being president," Time.com reports the participant said.

Concerns exist that Obama "will decimate moral values," said Mat Staver, chairman of the Florida law advocacy group Liberty Counsel.

The support is a welcome break for McCain, who had earlier been held at arms' length by leaders of the large conservative Christian community, which strongly supported President Bush in his elections.
