I actually agree with Mark Shields on this. Republicans, especially in the Senate, love to criticize President Obama when it comes to Ukraine. They blame him for everything from Ukraine to earthquakes thousands of miles away in Asia and perhaps every other problem that has arisen during his presidency. Depending on the day of the week, he is either ineffectual or dictatorial. However, Republicans never propose alternative solutions and seem bereft of ideas that could have prevented this or that crisis from happening. Their policy is built on soundbites and talking points and words like tough and decisive, without any real meat on their bones.
