I've had an unconfirmed transaction for over two weeks. 

I noticed there was a period where it was dropped from blockchain.info but still showed unconfirmed in my electrum wallet.  Then a couple of days later it seemed to have been rebroadcast somehow.

Some questions

- Does electrum rebroadcast everytime I open my wallet?
- Can I do a double spend to a new output with a higher fee.  (I've made other arrangements for payment since the original payment is still stuck).  Anyone have a good tutorial how to do this?
- viaBTC is not really a solution in my case.  I just want the original transaction to be dropped.
