Democrats have boasted recently that Cruz has only done them favors. Sen. Chuck Schumer (D-NY) said last month that the Texas Republican's 21-hour talkathon aimed at defunding Obamacare "advanced our cause."
After the government shutdown came to an end earlier this month, Reid said Cruz "can't talk down to anyone anymore."
