Eric Swalwell has a great new ad that gets right to the heart of what’s wrong with Donald Trump going back into the White House: his senility. Sure, he belongs in federal prison but while we wait on the criminal justice to sentence him for the 34 felonies he’s been convicted of and to try him on the dozens remaining, this man is already stark, raving GAGA. The ad, published by MeidasTouch, shows a “Grandpa Trump” worrying his family as he rants about “eating the cats,” executing babies and “Big, massive, dumps!” at the dinner table.
