From the Morning Memo:

And Sen. Bill Larkin made five.

Larkin, a 90-year-old World War II veteran who whose state Senate career began in 1990, is expected today to announce he will not seek re-election to the chamber, making him the fifth Republican lawmaker to do so, sources on Wednesday said.

Larkin is expected to make the announcement at 11 a.m. in Newburgh.

The retirement is also another seat Republicans will have to defend where Democrats hold a large enrollment advantage of more than 15,000 registered voters over the GOP.

It’s not a position Republicans necessarily want to be in facing the political headwinds of 2018 and Democrats are practically giddy over the prospect of a “blue wave” this year.

Democratic Assemblyman James Skoufis has eyed the seat for several election cycles and is considered a potential candidate to replace Larkin.

But Republicans have an insurance policy with Tom Basile, a former state committee official who has been raising money in case Larkin was not seeking another term this year.
