Many Americans watch the Super Bowl for the commercials. One ad that has generated a lot of interest features Heisman trophy winner Tim Tebow.

The born-again Christian and his mom are in a pro-life commercial, speaking out against abortion.

While pro-choice groups have complained about the ad, it's also getting its share of support.

The Susan B. Anthony List, which describes itself as "the nation's leading advocacy group for pro-life women in politics," has started an email effort called "Block Hard for Tebow."

Already, the group has received more than 50,000 comments of support.

SBA List President Marjorie Dannenfelser appeared on the Friday edition of the CBN Newschannel's Midday program to share more about the effort. Click play for her comments.
