Tough Defenses but successful
GOP - Colorado, Maryland, Arkansas, Nevada, Minnesota, Alabama, Georgia, Rhode Island, Florida, Hawaii
DEM - Oregon, Illinois, Pennsylvania, Kansas, Oklahoma, Arizona, Wyoming, Maine, New Hampshire
I'm going a little against the grain in Colorado and Illinois. I made a wildarsed guess with Hawaii wen I went with the incumbent. Oregon was a very tough call with the split democrats there, but usually they find a way to win.
I couldn't find how to transfer my gubenatorial map (RepublicanMich) to this, so I used a modified "Elec College" map shading out "tossups" as non-contests.
