下面四段都是出自同一篇文章：
http://ppt.cc/~S9a
In a remarkable reversal of fortune the man who removed Morsy from power -
then army chief Abdel Fattah el-Sisi - is now heavily favored to win the
presidential election.
不理解的地方在in a remarkable reversal of fortune.....
这段话是指el-Sisi因为是出自军方，所不是从显赫的财富阶级体系出生的人吗？
另外是为什么，in a remarkable reversal of fortune跟the man中间没有逗号？
读起来有点不顺。
To establish stability Egypt's next president must make tangible improvements
to the economy, improve security, and address mounting criticism from rights
groups and pro-democracy activists who fear a return to a Mubarak-era style
police state.
这段跟上面我第二个问题一样，为什么在to establish stability后面没有逗号呢？
为了建立稳定，埃及下任总统必须要真正改善经济（翻得不好…以下略）
The Muslim Brotherhood is not represented in the election, which is due in
large part to an aggressive campaign by Egyptian authorities to eliminate the
movement from Egypt's political landscape.
El-Sisi is heavily favored to win due in large part to widespread support
from Egypt's powerful establishment, which includes the military, the private
and state media apparatus, and Egypt's political and financial elite.
这两句第一行都有个due in large part 有点不太懂这个词组的意思。
大部份归因于…的意思吗？
谢谢回答。
