Obama's biggest vulnerability will be the general Democrat's inability to take a huge war chest and stay on their message.

From the left point of view:

- They screwed up health care by eliminating the public option and totally missing the "soud bite" appeal of "Medicare For All"

- They 'mumble' when it comes to Afghnistan troop withdrawals.

- They caved to the GOP on extending the Bush tax cuts to those making over $250K

- They caved on gay marraige.

- They caved on finance reform.

- They caved on Wall Street regulation and almost caved on consumer protection laws.

For all their money, they can't seem to out-buy legislators who have already been sold to corporate money.
