Rove advises Obama

Memo to Obama: win Iowa or lose the race — Rove offers six things Obama should do in order to beat Hillary Clinton.
If she wins the nomination it will be because her rivals – namely you – were weak when you confronted her and could not look her in the eye when you did. She is beatable but you have to raise your game. Iowa is your great chance for a breakthrough. Win it convincingly and you can build on it in the contests that follow. Lose it and victory becomes much more difficult.
