MSNBC's Rachel Maddow on The View -- (ABC screencapture)

Tuesday night MSNBC host Rachel Maddow was incredulous that the GOP could control both houses of Congress and the White House and still not get it together enough to make good on their 7-year-old promise to "repeal and replace" Obamacare.

Maddow broke it down, part by part.

“Even as we’re following this day by day, and sort of hour by hour now, stepping back from this for a second, this is a remarkable place where we have ended up. Right? In this last election, Republicans got control of the Senate," Maddow explained. "They got control of the House. They got control of the White House, and even with that total control in Washington, they really are about to hit six months in power, which technically, I think it will be Thursday of this week. By the end of this week, it will be six months in power."

Republicans in control of all branches of government, and they will have not passed a single substantial piece of legislation" she said with a smirk.

"I mean, they can pass basically anything they want with zero Democratic votes. They only have to line up votes in their own party, and still, they have passed nothing," she added. "Even this one thing they campaigned on for seven straight years and practiced doing impotently dozens of times while President Obama was in office. Even this one thing, they really do not appear to be able to do it.”
