I've been receiving multiple robocalls per day from the O'Donnell and Castle campaigns for the last week. We're really sick of them and they are not convincing anyone in my family to vote for a particular candidate. I'm already voting for Castle. O'Donnell doesn't have anything to recommend her other than conservatism. Conservatism won't win her the general election. On the other hand my politically neutral wife is pissed off enough that she probably won't vote in the primary. If the Republicans keep it up, she might vote Democrat to spite them.
It has me wondering if the Delaware Republicans even know how to campaign properly. Two years ago, my long-incumbent state representative Vince Lofink lost the election to Democrat Earl Jaques. This is largely because Jaques and his wife did their legwork. They went door to door. He hit every HOA meeting in the district. People knew who he was and voted for him. Two years later and Earl has already knocked on my door and will almost certainly be at my HOA meeting. The Republican candidate? Still haven't met him. I expect Jaques to win re-election quite handily unless things change after the primaries.
Campaigning requires real legwork. Robocalls are fake legwork. This is why people are annoyed.
