That's the number of aldermen Mayor Richard Daley will have appointed to the Chicago City Council once he decides who will fill the seats vacated by Manny Flores and Ike Carothers this year. If Ald. Toni Preckwinkle wins today's primary and is elected Cook County Board President in November, you can add another one to the list. Not every appointee is a rank-and-file Daley supporter, of course.  And the large majority have been reelected on their own merits.  But still: 19 seats represents a whopping 38 percent of the council. When it only takes 26 votes to approve an ordinance -- and 17 to block a (rare) veto override -- it's quite an advantage for hizzoner.
