In 1854, the Republican Party was founded mainly to end slavery, and for two decades it honorably promoted African-American equality. Its first presidential nominee, pioneer James C. FrÃ©mont, took a staunch anti-slavery stand in 1856 and ran well, paving the way for Abraham Lincoln's election four years later. Lincoln was no radical. He believed white men superior to blacks and opposed the outright abolition of slavery.
1 In a twin pregnancy. the average is 37 weeks. for triplets 34 and quadruplets 32 weeks.  The average birth weight for singletons is 7 lbs 7 oz. Average birth weight of twins is 5 lbs 5 oz. for triplets 4lbs and quads 3lbs. A difference in birth weight between multiples is not unusual.
The risk of preterm labor and premature birth are heightened when there is more than one baby in the womb. Other conditions such as preeclampsia, placental dysfunction, and TTTS are more prevalent in twin pregnancy and increase the risk of an early delivery. Research from the National Organization of Mothers of Twins Clubs (NOMOTC) indicates that about half of multiples are born before 36 weeks gestation. An informal, unscientific poll on my site indicates 18% delivered before 28 weeks and only 15% after 38 weeks.
