HARRISBURG — Rick Santorum says he hopes to say soon how he will continue to press for conservatism in politics.

Santorum and his wife, Karen, spoke Monday night on a half-hour conference call to thank supporters, and didn’t reveal whether he’d eventually endorse all-but-certain GOP presidential nominee Mitt Romney.

But he insisted that money woes were only a small piece of the story behind his decision last week to drop out of the race.

He didn’t name names, but said efforts to win backing from other conservatives in the race failed, as did an effort to persuade Texas’ Republicans to award delegates on a winner-takes-all basis. That left him without a clear path to victory.

He also said that his 3-year-old daughter’s hospitalization had heaped stress and strain on the family.
