VOA 《Georgia Vote Tuesday Seen as Crucial for Biden Presidency》

Volunteers like Cara Allen and Sean Watkins are a big part of the democrats strategy, for reaching out to the younger more diverse voters who have reshaped the state in recent years.

I actually wasn't into it wasn't that much into politics like maybe two years ago. (事实上，两年前，我并不热衷于政治)

为什么这里用了for reaching...来表目的，通常表示目的不是应该用不定式例如to reach或in order to reach...吗？

可是这里用for doing = for reaching 表目的是为什么？ 顺便请教老师wasn't that much into politics 中that much 是副词+副词，作表语吗？
