You're being ridiculous. You will probably see that Romney won West's district, so you can't blame anyone other than the candidate's weakness or his opponent's strength.
Just what did you do for West? Did you even donate directly? Did you hop a bus and go volunteer? Bad news, friend, the GOP is you and if you didn't make much of an effort, why would you expect your neighbors to?
Take a breather. This is a very winnable district in 2014. It will be highly targeted and the NRCC will put a lot of effort into getting it back; count on it. If West plays his cards right, he'll be back in congress within two years.
Your assessment is spot on to a large degree. I don't know how Obama did in Palm Beach within the 18th district. However West lost the 18th district by a poor showing in Martin Cty. Obama lost Martin by some 18,000 votes and West only won by some 10,700 votes. Had West carried Martin in the same range as Romney did we'd not have even heard a thing about St. Lucie Cty.
Martin Cty.... West by 10,700 {Romney by 18,000}
Palm Beach ... West by 200
St Lucie . .... Murphy 12,800
Numbers are rounded but close.
