We went from having a super majority in the Senate and large majority in the house and plus having 29 Governorships plus many state houses during Obama's first term to now only having 48 Senate seats, 192 House seats, 15 governorships and a small minority of state legislators and now we lost the Presidency.
Will the left now finally realize that the current way of thinking will not allow us to win?
Democrats never had a super majority in the Senate. At most with 2 independents, they had 59 Senate after Specter switched parties. However, given ongoing MN Senate recount and court battles and Kennedy's health, they really only had around 57 active voting Senators for most of 2009. So it was extremely difficult to get anything done. Lieberman and Nelson from NE were mostly the reason there was no public option in the PPACA.
I believe the last time any party had a super majority was the Dems after the 1936 election when they had a whopping total of 75 seats. They actually had a veto proof majority of 69 after the '34 midterms.
