"There are two parts to this story:

"The first one is the celebration of Marco Rubio as our party's nominee. Never in our party's history have we witnessed a 65-plus point swing in a statewide campaign involving two well-known candidates. Kudos to him. Marco has risen to become a darling of Republicans nationwide and is the heavy favorite to become a U.S. senator before the age of 40.

Charlie Crist and Marco Rubio tangled before a national audience on "Fox News Sunday," and Republicans say the debate reinforced "defining differences" between the U.S. Senate candidates.

It also raised concerns among state party leaders.

Will Sunday's Fox News showdown between U.S. Senate candidates Gov. Charlie Crist and Marco Rubio be fair and balanced?

Both men are telegenic and smooth -- even slippery in the best political tradition -- and neither camp is losing an opportunity to frame the impact of "Fox News Sunday With Chris Wallace," which will air live from Fox News' Washington, D.C. bureau (check local listings for times).
