I don't think anyone noticed, but during all the commotion of this past weekend, Gillibrand announced her candidacy.
Nice judgment exhibited right there on her part -- especially since she already announced it on March 17th.

Oh WAIT!!, she also announced back in January:

Maybe she will announce her candidacy every Sunday until someone, anyone, notices.
