Of course, we don't even know if Miller will be the nominee. He is in a GOP primary against ex-Winter Park Commissioner Karen Diebel and state Rep. Sandy Adams, two candidates with more electoral experience than the Ruth's Chris flunky. But if they can beat the well-monied Miller that probably means they can go into the general election strong. With news of the NRCC incumbent-killing program targeting her but ignoring Ron Klein, I suspect this makes Kosmas the most vulnerable incumbent in Florida this year. And since Obama lost this district two years ago, many people such as Southern Political Report are already moving this into the leans Republican column.
But then, Kosmas is still winning in money, and will build up some good name recognition and voter support in a minor primary with former Winter Springs mayor Paul Partyka. This is a big media market, so money could make a huge difference. Kosmas can definitely stick this out, and from there develop a long-term career in Congress. But it won't be easy.
