Compressed primary schedule works to Clinton's advantage

More than half of the delegates to the Democratic National Convention will be chosen Tuesday and that works to Hillary Clinton's advantage, according to an article in today's Washington Post.
Her competition, Sen. Barack Obama, fares better when he has more time to personally campaign, the article indicates:

Polling and election results so far suggest that the more time Obama has to present himself to voters, the better he fares. In each of the first four states where voting was sanctioned by the Democratic National Committee, Clinton maintained essentially level support in polls in the months leading up to the contests, while Obama saw a steady upward trajectory the more he campaigned. In Florida, by contrast, where the candidates did not campaign after the DNC punished the state for moving its primary to January, Clinton soundly defeated Obama, offering a rough gauge on how much the senator from Illinois relies on voter contact.
