McCaskill relayed some fun family vignettes this morning, and promised to talk more about her mom throughout the day.

McCaskill tweeted on her mom's intelligence:
Today I will only tweet about my mom. She's special and amazing. Strong and opinionated. Street and Jeopardy smart.

I have two sisters, one brother. Growing up my mom would get us in the station wagon by yelling "Last one in the car is a Republican!"


And on her own plans for Mother's Day:
Taking Mom to brunch today. Then my son(only one home from school) taking me to Star Trek. And it's a beautiful day.
