"There's never been a day in the last four years I've been proud to be his vice president."

The Weekly Standard (linked by Drudge) thinks it has a hilarious Biden gaffe, but they've misheard/mistranscribed it. You have to have an ear for the "working class"-style mushing of syllables, but he's saying "There's never been a day in the last four years I haven't been proud to be his vice president." The boldface is spoken: I 'n' been.

IN THE COMMENTS: rhhardin says:

I've listened to the audio at 0.35 speed and it's a precise "I've."...

I disagree.

It's an east-coast kind of "n" ... sort of almost "i uh" like the "no" in "uh uh."

rhhardin says:

"n" is voiced and there's no voicing in Biden's 've part.

I note that I grew up in Delaware and I feel I understand the implied "n." And rh gives us his slowed down audio with repetition. I've listened, and I hear a sound after the "I" that I'm sure is the negative. There's this southern Jersey/northern Delaware/Philadelphia dropping of a sound that I can her. There's a muddled verb after the "I" that I just know. Rh says "Call in Language Log," and I will send an email. I think they will believe me. And not just for political reasons.

UPDATE: Language Log responds!
