The National Republican Senatorial Committee (NRSC), the Senate GOP's campaign arm, will hand out “baseball cards” mocking Sen.

The NRSC said in a statement that the cards will highlight how Peters “remains the most unknown senator in the country because he has failed to stand up for the principles and priorities of Michigan voters.”

There will be five cards, all of which intentionally give Peters an incorrect first name, including "Jerry Peters, aka The Invisible Man," "Larry Peters, aka Motorcycle Guy," "Barry Peters, aka Socialist's BFF," "Terry Peters, aka K-Street's Favorite Hypocrite," and "Harry Peters, aka He's Just There."

The NRSC’s statement linked to a

of 600 likely Michigan voters which found that about 36 percent had not heard of him and a

Morning Consult poll

which found that 40 percent of respondents had no opinion of him.

"Michigan voters are encouraged to collect all five baseball cards to learn more about Peters' lack of accomplishments, hypocrisy, and associations with the most radical members of his party," said NRSC spokesman Nathan Brand in a statement.

In response, Michigan Democratic Party spokesperson Alex Japko went after a prominent contender in the Republican Senate primary and defended Peters' record of accomplishments.
