Mitt Romney made no secret during his two presidential campaigns of the admiration he held for his father George -- a car executive, governor of Michigan and Republican presidential candidate in 1968.  In "Mitt", a friendly documentary about the 2012 campaign, Romney reminisces about how much harder his father had it than he did, building a business and a political career from scratch.

Here's how Boston Globe reporters Michael Kranish and Scott Helman described the differences between father and son in their book "The Real Romney":

Alike in so many ways, George and Mitt Romney had distinct views of politics.George was famously headstrong and outspoken, willing to follow his gut where it took him.. . . If George Romney shot from the hip, his son, before he shoots at all, carefully studies the target, lines up the barrel just right, and might even fire a few practice rounds. Mitt Romney, who saw the shortcomings of his father’s approach, has often been more inclined to identify the consequence he wants, then figure out how to get there.

The photo above is one of handful of images captured by Time-Life photographers of the Romney family in their native environment. This photo, taken in 1957, shows Mitt Romney, age 11, sitting with his dad, who bears an absolutely uncanny resemblance to the current version of Mitt, age 67.
