2012 Predictions

Using the same predictive model as for 2008. It only predicts states trends regardless of national swing, so it just gives a rough outline of what to expect. Also, I'm also predicting what the electoral college votes might be as they will be changing as a result of the 2010 census.
-
No Change, Obama gets the same national vote in 2012 as in 2008.
Obama - 52.8% - 301 EV
Republican - 45.7% - 159 EV
Toss-Up - 78 EV

Note: Compared to the 2008 result, considering <5% a toss-up, North and South Dakota move from Republican to toss-up, Montana and Indiana move from toss-up to Democrat. However, due to changes after the census, Republicans would probably pick a handful of electoral votes despite no favorable shift in state trends.
-
Obama does as well as Bush Jr. and Clinton, gains 3%.
Obama - 54.3% - 334 EV
Republican - 44.2% - 144 EV
Toss-Up - 60 EV

-
Obama does as well as Reagan, gains 8.5%
Obama - 57.1% - 376 EV
Republican - 41.5% - 83 EV
Toss-Up - 79 EV

Note: There are two reasons why this map doesn't look like Reagan's 49-state sweep map. First, Reagan won by a larger overall margin. Second, there was less variance among the states, consider in 1980, 50.8% got 489 EV, but in 2008, 52.8% got 365 EV. Basically, the two parties are much more entrenched in a number of states than in the past.
-
Obama does as well as Carter and Bush Sr., loses 12.5%
Obama - 46.6% - 204 EV
Republican - 52.0% - 251 EV
Toss-Up - 83 EV

-
Obama and Republican candidate have an equal chance of winning, Obama loses 9%
Obama - 48.3% - 219 EV
Republican - 50.2% - 219 EV
Toss-Up - 100 EV

Note: In order for Republicans to have an equal chance at winning the electoral college, they have to win the popular by over 1.9%.
