Sources close to the campaign and family tell McKay Coppins that Ann Romney and her five sons urged Mitt Romney to go with his gut and pick Rep. Paul Ryan as his running mate -- even as most of the other campaign advisers expressed their doubts.
"Romney, who has long trusted his wife's 'people instincts,' gave
substantial weight to her endorsement, which, combined with his own
personal preference for Ryan, was enough to overrule his advisers'
concerns."
