Mitt's Hostile Leveraged Take Over of the Nomination

Why is anyone surprised that Mitt Romney is waging a horribly negative campaign to win the RepubliCant nomination for the presidency of the United States of America?  His much touted professional career was in investment banking.  But there are different parts of investment banking.  There is the Warren Buffet kind where you buy and hold a company and make money from buying sound companies.  Mitt did this for a little while.  Then Mitt found out you can make a whole lot more quicker by buying companies with that company as collateral.  Then you without the present owners consent take it over.  This is a HOSTILE LEVERAGED TAKE OVER and that is what Mitt is doing with the RepubliCant presidential nomination
