From the Morning Memo:

Democrat Michelle Hinchey this morning will launch her bid for the 46th Senate district in a challenge to incumbent Republican George Amedore.

The district is spread over the Mohawk Valley, turns into the suburban Capital Region and snakes down to the Hudson Valley.

It was drawn as an added Senate seat by Republicans in 2012, designed at the time to bolster the party’s thin majority in the chamber.

But voters had other plans: Democrat Cecilia Tkaczyk narrowly won the seat that year against Amedore, then a member of the Assembly. Two years later, Amedore won the district by a more comfortable margin.

With Democrats holding a large majority in the chamber, focus in the early going will likely to be on battlegrounds on Long Island and western New York, where Democrats hope to further play offense. But the 46th Senate district, which overlaps with the perennially competitive 20th Congressional district, could once again be a closely watched seat.

Democratic voters, emboldened by a push to oust President Trump, could play a factor in down-ballot races if they come out to vote next November. But Republicans, especially in upstate counties the president won three years ago, could still be the difference if some races are close.
