Valentine's Day on Thursday has the Republican National Committee thinking very sour thoughts about Democratic presidential hopefuls Sens. Barack Obama and Hillary Clinton. To note the day, the GOP has issued six Valentine's Day cards for the two, and they aren't the stuff of love and dreams. "Roses are red, violets are blue," says one shown to Whispers, "I'll raise your taxes and there is nothing you can do." For Obama, one reads, "Three years in the U.S. Senate qualifies me to wish you a Happy Valentine's Day." Check all six at the RNC website.
