Our intrepid producer Jacob wanted to know why she decided to embrace the viral mockery instead of running from it ... and she tells us it's because she's "authentically Michigan."

Rep. Stevens explains ... she's a reflection of her constituents back home.

The campaign ad featured an amped-up Stevens promising to fight for Michiganders with "a little bit of joy, a little bit of enthusiasm, a little bit of energy, and a little bit of stick it to 'em" ... before declaring, "That's the Michigan way."

Her delivery became an easy target online ... but Rep. Stevens isn't backing down ... and she also takes a shot at President Trump.
