Here it is, this week's installment of our favorite online political videos. Dig in for a video from liberal commentator Jim Hightower, a new song from the folks who brought you Obama Girl, fun with tagging, an explanation of just what is going on in the Iowa caucuses, John McCain's celebration of his "I was tied up" remark, and more.

As always, your suggestions for the week's top videos are welcome. Send them to info AT techpresident DOT com.

Chris Dodd gets dugg; Glenn Greenwald has high praise for Chris Dodd and harsh words for Barack Obama and Hillary Clinton; Compete.com develops new charts to show where the candidates lie on the political spectrum; a new faux-od (fauxde?) to Ann Coulter from the makers of Obama Girl; two new excellent reports from Off The Bus; Generation Engage fails to engage the top tier of the GOP; and Jose Antonio Vargas does video with young voters.
