Republicans lost pretty convincingly this time, in part because they started believing their own bullshit. Because they were wackos who thought Obama was an Anti-colonial Kenyan Socialist Muslim they became convinced that everyone would. They catered to their feverish, Christianist, elderly, uneducated and often racist base in ways that offended a whole lot of other people.
When polls started showing that their bullshit wasn't working, they tried pretending the polls were a liberal conspiracy. Well, reality bit. And it continues to bite in lots of ways. Unfortunately, the idiots are not the only ones who get washed away in the floods.
