Scott Walker puts an exclamation point on his terrible, horrible, no good, very bad week

As quoted in Scott Walker says Islamic terrorists harmful to 'handful of reasonable, moderate followers of Islam'. (Capital Times, 8/21/2015)

OK, Retiring Guy has some questions.

How much is a handful?  (halphasian, 3/13/2010)

You could also use "handful" figuratively to refer to a relatively small number, probably between 3 and 7, but possibly more depending on the context: "I've had a handful of opportunities to travel abroad" or "There are only a handful of people in the world who know how to use this software." You can't actually hold opportunities or people in your hand.

How many Muslim are there in the world? 

Islam is the world's second largest religion. According to a 2010 study and released January 2011, Islam has 1.57 billion adherents, making up over 23% of the world population. According to the Pew Research Center in 2015 there were 50 Muslim-majority countries.  (Wikipedia)

What's this about Walker's foreign policy cred?
