Seeking to end the campaign for the Democratic nomination on Tuesday, Senator Barack Obama is using his large money advantage to overwhelm the Clinton campaign in a blizzard of advertising and a huge get out the vote effort.

American Thinker political correspondent Rich Baehr who has been in Cincinnati for several days reports that Obama ads are all over radio and television while Hillary's media presence is non-existent.

And the New York Times reports that Obama is clearly looking for the knockout blow:

The intensity of Mr. Obama’s drive is especially apparent on television, where he has outspent Mrs. Clinton by nearly two to one in the two states. That is helping him eat deeply into double-digit leads she held in polls just weeks ago.

But after a month in which she raised $32 million — a remarkable amount, but still less than the $50 million or more brought in by Mr. Obama — Mrs. Clinton is fighting back.

The expenditures of the two Democratic presidential candidates, combined with a travel schedule that sent them and their surrogates from border to border in Texas and Ohio, reflect the expectation that the voting this week may be climactic.

Mrs. Clinton’s advisers have suggested that she will bow out of the race if she falters in either state, after 11 straight losses.
