Yesterday on the floor of the US House of Representatives, Republican Congressman Tom Marino correctly observed that when Democrats (under Speaker Nancy Pelosi) held the House, the Senate, and the presidency they did nothing to address the issue of illegal immigration. Ms. Pelosi was so incensed at this accurate statement that she chased Congressman Marino around the House Chamber, screeching and calling him names (or at least, adjectives). [Video at link]
So, the Democrats in the Senate are led by Harry Reid, a very elderly man who appears to be succumbing to the onset of senile dementia with his endless deranged rants against the Koch Brothers and passing clouds. And in the House, the Democrats are led by an elderly deranged woman who chases people around the chamber screeching at them and calling them names.
The Roman Senate under Caligula had more decorum.
