If you've had it with disparaging political rhetoric, look to this group of true leaders who don't place the blame on one another when times get tough -- they solve problems.

The NonProfit Times has announced its Power & Influence Top 50, recognizing the top leaders in the nonprofit space.

In its 15th year, the honor recognizes those who -- in the face of a global economic slowdown, austerity measures and other challenges -- have embraced change to create change. And many of them are HuffPost Impact bloggers!

Vicki Escarra of Feeding America tackles hunger issues as child homelessness, among other problems, increases. And Ben Rattray from Change.org has proven how technology is one of our greatest tools in mobilizing around a cause.

Read in the slideshow below about these notable nonprofit leaders who also share their thoughts as bloggers on HuffPost. Then, check out the full list at The NonProfit Times.
