The latest signs that Mitt Romney is likely to run for president in 2016 may come as welcome news to former aides and supporters, many of whom received phone calls from the former Massachusetts governor this weekend.

But the prospect of another Romney campaign failed to capture the hearts of social and fiscal conservatives gathered this week in the nation's capital to hammer out the policy agenda for the new Republican-controlled Congress.

The two-day "Opportunity for All, Favoritism for None" conference was hosted by the Heritage Foundation, an influential conservative think tank. The event brought together activists and Republican lawmakers looking to promote conservative solutions on education, defense, religious liberty and marriage -- issues that potential 2016 candidates will need to tackle ahead of what is shaping up to be a contentious primary. But when asked about Romney, an establishment Republican who failed to unseat President Barack Obama in 2012, several attendees said thanks, but no thanks.
