AC Kleinheider sums things up nicely

People will continue to opine that this is evidence of a fear. A fear that Ed Bryant is stronger than the polls presently show. I really don’t think this is the case. I believe strongly that the Corker people are confident as to their victory.

This is a move to move funds into his campaign before the general election so that Harold Ford is precluded from the higher individual contributions limits that are now available to Van Hilleary and Ed Bryant.

Corker is looking to run up the score. Winning is a relative thing. If Corker wins narrowly, he can be seen as weak as not supported by his party. This makes him vulnerable in the general.

Bob Corker is no longer running in the primary, even if it looks like he is. He is running in the general.

And part of winning the general election is winning the primary by the greatest margin possible.

Ayup.

UPDATE Check that, Roger Abramson gives AC a run for summing things up nicely

Really? Bob Corker’s pumping some cash into his campaign in the final primary election days?

Well, despite what your star closer in the ninth inning to protect a lead. He’s slamming the door.

Or trying to anyway. We’ll see. In any case, anyone who thinks Bob Corker’s somehow getting desperate is officially divorced from reality.

Further, ayup.
