Obama on Vouchers

I couldn't improve on this analysis of Obama's statement as to whether he would support vouchers:

Take the question of how many kids would leave government schools for private schools under a full school competition system. Obama wants to be on both sides of this assumption, sometimes assuming the number is small (when discussing benefits) and then assuming the number is large (when discussing costs). Obama is a master because he makes this switch back and forth from sentence to sentence. First, the number leaving public schools is low, since choice would just benefit "some kids" (Bad old rich ones at that) and leave our "a lot of kids." He again in the next sentence implies the number switching must be low, because there are not many private school spots. One sentence later, though, the number switching is high, since it would be a "huge drain of resources." And then, in the third paragraph, the number switching is very high, since all that are left in public schools are a small core of the "hardest-to-teach kids."
