Obama Machine in full swing for 2014. His motivation will be that this will end up being his LAST CHANCE to REALLY push an agenda in his final 2 years in office (assuming that he won't get TOO much done between now and 2014 due to Republican obstructionism, although I'm hopeful).
A quick glance tells me that the following races are EXTRAORDINARILY winnable (no Republican won their district by more than 4 points, some by LESS than 1 point):
New York 27
That's nine. We need to flip at least 7 more for the majority (assuming that we win the 5 outstanding House seats, and I think we lead in each).
So... President Obama + his INCREDIBLE Ground Machine + US (working our asses off) = a Democratic House in 2014. It's doable, and would be MORE than worth it. I'd love to do my part to make President Obama's last two years REEEEEEEEEEEAAAAAALLY count.
