Romney: 42-Year Marriage Speaks to His Consistency

ROCHESTER, Mich. — Republican presidential hopeful Mitt Romney says he is not the flip-flopper his critics brand him and points to his marriage of 42 years as proof.

The former Massachusetts governor says Wednesday that he is "a man of steadiness and constancy." He was asked during a debate in Michigan why voters should trust him given policy shifts.

Romney says he is a steady presence and pointed to his marriage and the 25 years he spent at Bain consulting firm.

Questions about Romney's authenticity have dogged him during his second presidential bid. He has changed positions on issues such as abortion and gay rights. Democrats and his GOP rivals have sought to highlight those shifts on issues important to primary voters.
