The Democratic nomination went to Dukakis in mid-July, giving him an extra month before Bush's nomination in mid-August. Dukakis therefore had to spread out the use of his money over a longer time until the November election, but Bush was able to concentrate his general election spending over a shorter period. Bush's major media spending did not begin until mid-September, after he took the lead in the public opinion polls from Dukakis's preconvention status.
