...and you can too!
I found a cool website that allows the user to tinker around with the states to configure any number of potential election scenarios. The map is shown with 2012's electoral view in a tie, with Obama states in blue and Generic Republican states in red.
You can click on the map flip states to Republican red or Democrat blue depending on what you think might happen with any given match-up. States also can be flipped to neutral so you can account for potential toss-ups.
Perhaps most importantly, the tally for the electoral college changes in real time as you make changes.
For deeper analysis, you can compare with previous years' results (e.g. 2004 and 2000).
When you're done, you can share your map with friends via email, Facebook, Twitter, etc. with easy-to-use buttons on the page.
Here's my map for a narrow win for John Q. Generic Republican (with the map's URL below the image):
I think more than one of the Republicans running for president could pull off something like this, don't you?
If you want to share your own generic or candidate-specific map with the rest of us, I'll post it below...
PS: This chart is very helpful.
UPDATE: John wants to think big. Very, very big:
UPDATE II: Yikes! This one is very interesting.
