I don't really read politics or even watch the news anymore these days, but I did go see what she had to say and my only though is this....
I worked for the past 20 years in the Navy, retired and then became a SAHM{I had all of my children while I was on active duty} ....for me presonally, being a SAHM was harder and absolutely MORE work than I had done over 20 years of service! So I went back to work
but seriously I don't think you can really compare "working" moms , per say, to stay at home moms.....we all do are part whether we work full time or stay home full time ....one is just as hard and just as rewarding as the other
