Sarah Palin spoke candidly recently about her daughter Bristol’s second pregnancy, saying she understands how difficult it is for her to do “double-duty” as a single parent. However, Palin says she’s happy about the prospect of having a granddaughter.

Bristol–who called off her wedding to Dakota Meyer just a week before the nuptials were to take place–has six-year old son Tripp with ex Levi Johnston, and the fact that she’s an unwed mother is in direct opposition to pretty much everything Palin stands for politically.

“Well, the cool thing about puttin’ your faith in God is, He certainly is a God of second chances – and third, and fourth and fifth chances. I screw up all the time,” Sarah Palin said.

While Palin says she knows how hard it’s going to be for Bristol to pull both mom and dad duty for her kids, she’s also happy for her and says she can’t wait to meet her granddaughter.

“Being a single mom is, oh my goodness, my heart goes out to the single parents. But my enormous admiration for what it is that they’re able to accomplish doing double-duty. And I watch Bristol do double-duty all the time, you know, with her little boy, Tripp…I can’t wait for about 45 more days, and I’m gonna have a little baby granddaughter. And I’m happy about it,” Sarah said.

Bristol Palin said when she announced her pregnancy earlier this year that she was trying to be strong this time around and not let the opinions of others get to her.

“Honestly, I’ve been trying my hardest to keep my chin up on this one. At the end of the day there’s nothing I can’t do with God by my side, and I know I am fully capable of handling anything that is put in front of me with dignity and grace. Life moves on no matter what. So no matter how you feel, you get up, get dressed, show up, and never give up. When life gets tough, there is no other option but to get tougher.”
