The last poll showing an Obama-Clinton matchup is today, and shows Obama at 50% to Clinton's 42%.
However, while Senator Clinton has remained close and competitive in every meaningful measure, she is a close second and the race is over. It has become clear that Barack Obama will be the Democratic nominee.
At the moment, Senator Clinton’s team is busily trying to convince Superdelegates and pundits that she is more electable than Barack Obama. For reasons discussed in a separate article, it doesn’t matter. Even if every single Superdelegate was convinced that the former First Lady is somewhat more electable than Obama, that is not enough of a reason to deny him the nomination.
With this in mind, Rasmussen Reports will soon end our daily tracking of the Democratic race and focus exclusively on the general election competition between Republican John McCain and Democrat Barack Obama. Barring something totally unforeseen, that is the choice American voters will have before them in November. While we have not firmly decided upon a final day for tracking the Democratic race, it is coming soon.
