Nobody predicted a landslide victory for Romney. You made that up.
If you ran for president as a democrat, you would likely win over 250 electoral votes. That is why there is never a landslide, especially for republicans. Republicans will never win California or New York or most of the northeastern states or Oregon or Washington. You must have seen the red and blue state maps. Some states are always going to support the democrat, no matter how awful they may be. Some states will always support the republican candidate, whether it's Romney or Trump. Swing states are balanced enough to go red in one election and then go blue in the next election. That is changing to some degree with the huge growth in the Hispanic population. The majority of them vote for democrats. They will help Hillary win Florida and Ohio. In the coming years, democrats will win in Arizona and even in Texas, mostly because of Hispanics registering to vote in record numbers. I doubt republicans will ever win the White House again.
Not that a President should be blamed or applauded for what happens while he is in office, I think any intelligent person would admit that the country is a mess these past 8 years. Growth in GDP is the worst is has been since the depression. Unemployed people have given up looking for work and the result is the lowest work force participation rate in many decades. Our enemies have no fear of a feckless commander-in-chief, and attack us at will. We have no solid allies. The borders are essentially open. The only people who should be celebrating this administration are pot smokers, who love the fact the feds have decided not to enforce drug laws. Your comments are totally void of fact and reason.
