Ask a liberal what he thinks of shutting down the government out of principle. The answer would probably be unprintable. Ask the same liberal what he thinks of last month's filibuster by U.S. Sen. Ted Cruz, R-Texas. Same answer.
Yet the same liberal likely would applaud Wendy Davis, the Democratic state senator who shut down the Texas legislature this summer out of principle. She did it with a filibuster.
Ask a liberal what he thinks motivated Cruz to spend 21 hours talking on the Senate floor. The answer would probably be that Cruz has ambitions for higher office — the White House.
What motivated Davis? Surely it was her principled opposition to restrictions on abortion. Maybe not. Davis isn't just considering a higher office. She's seeking it. She wants to replace Republican Gov. Rick Perry in the state that not only elected Perry three times but sent Cruz to the Senate.
Neither Cruz nor Davis succeeded in effecting the change they sought. Cruz wanted to defund Obamacare. Davis effectively ran the clock out on a special session, but the legislation she opposed was enacted anyway in a subsequent special session. Still, they did make a name for themselves.
