Four mistakes , that in your opinion are mistakes . Patriot Act was a no brainier after 911 and republicans rammed that through congress so fast to play on the nationalistic fervour in the wake of the attacks . He voted for the Iraq war on the back of faulty and intentionally misleading intelligence put forward by the republican administration . Shouldn ' t voting against Obamas Iran Deal make people on the right love him ? Here ' s the crazy thing . Unlike the GOP , the Democratic Party is made up of a wide spectrum of centrists that don ' t vote in a single bloc . It would be refreshing to see the republicans try that from time to time . He ' s not perfect , but he represents his constituents and they keep sending him to DC .
