Sep 04, 2008 — Sarah Palin left Republicans energized and excited last night as she made her case for the vice presidency, and laid out why John McCain should be elected president. She used her speech at the GOP convention in St. Paul to make repeated digs at Barack Obama, the Democratic candidate. She said McCain is exactly the kind of man she wants in the White House. McCain made a surprise appearance on stage after Palin's address last night. Martha Foley has more.
