He said he would deal with immigration reform in the first year of his term; we would become legal via such legislation. However, he did not do anything = liar!!!

You can try to defend him by saying that the economy was awful, and, as a result, he had to prioritize progress. Excuse me. The economy is just as bad now or evern worse, so why is he trying now? He is a liar, and he clearly contradicts himself.
