Pawlenty is the star of a classic up-by-the-bootstraps story. The grandson of German immigrants and the son of a milk truck driver father and a stay-at-home mom who died when he was 16, Pawlenty is one of five children raised in a working-class St. Paul neighborhood and the first in his family to attend college. After a difficult chemistry class rerouted his dream of becoming a dentist, Pawlenty became a lawyer, dabbled in business, and entered local and state politics. As Minnesota governor he balanced the state鈥檚 $4.3 billion deficit without raising taxes and was on the short list to become John McCain鈥檚 running mate in 2008.
