As president, which candidate would best serve public education?

Every presidential candidate in the 2008 elections vows to improve education, but which one has the best plan to get the job done? When it comes to the controversial No Child Left Behind Act, Mitt Romney, John McCain, and Mike Huckabee generally support it; Hillary Clinton and Barack Obama want it drastically overhauled; and Ron Paul would scrap it altogether. The candidates have taken strong stances on everything, from universal pre-kindergarten to merit pay to private school vouchers. Whose vision best matches your own hopes for education in America? We want to know! (Candidates are listed alphabetically, and political affiliation is indicated after each name.)
