Our favorite videos are back! This time around, the increasingly non-threatening Joe Biden gets quoted by his opponents; John Edwards posts a couple of strong campaign videos; Mike Huckabee gets a strong endorsement and a curious phone call; and a new Mike Gravel video suggests a new career might be awaiting the former Alaska Senator. All this and more after the jump.

I'm glad that TechPresident blogger David All posted the "I've Got a Crush...on Obama" video this morning, because it opens up a discussion that Josh Levy and I started having yesterday when we got the same email tip about the video that I presume David got. First off, do watch the video--it's hilarious, the lyrics are priceless ("You're into border security...let's break this border between you and me...Universal health care reform...it makes me warm"), and BarelyPolitical, the comedy team that wrote the music and filmed the video, should probably get hired by Saturday Night Live. (They're up to nearly 30,000 views on YouTube, by the way, as of this morning.) But is this a political video mashup or a job application? And in this day and age, should we care if it's both at the same time?
