请教老师：

With many lawmakers facing tough reelection races,

the incentives to work with the other side are few.

不定式作定语。

With many lawmakers facing tough reelection races,

the incentives to working with the other side are few.

介词to working.

这样又变成了什么意思呢？

怎么感觉这里用to work, 或to working是一个意思呢？

请教老师分析讲解，谢谢！
