The way people feel about a particular candidate the moment they enter the voting booth can also factor in, and according to CNN 10 contributor

Tyler mauldin so can the weather.

1) The way people feel 是什么意思？ 其中the way这是什么用法和词性？怎么理解这里的the way ? 没搞懂。

2) factor in的宾语是提前了吗？ 宾语是整个“The way people feel”吗？

3) so can the weather 是否 需要说成so can the weather do ?

麻烦老师帮我详细分析！谢谢！
