For the first time since 2001, Schumer's approval rating has dipped below 50 percent.
The most recent Marist poll reported that 47 percent of registered New York voters think Schumer is doing a good job in office, while 31 percent rate him fair, and 17 percent say his performance is poor.
In the last few months, Schumer's approval ratings have been steadily decreasing. In a Marist poll from Jan. 15, 51percent of New Yorkers rated Schumer average, compared to 54 percent who rated him good in November, and a 66 percent great rating back in September.
"These are tough times and polls go up and down but the last time the Senator's numbers were in this vicinity was in September 2004, two months before the voters overwhelmingly re-elected him, said Schumer spokesman Josh Vlasto in an e-mail.
But the GOP shouldn't start celebrating yet.
If the November elections were hypothetically held today, Marist reported that despite the approval rating, Schumer would still win against potential Republican candidate, CNBC anchor Larry Kudlow, 67 percent to 25 percent, respectively.
Schumer, who has held his senate seat since 1998, saw his lowest approval rating at 39 percent in March 2000.
