Why Not Gretchen Whitmer?

While Michigan Gov. Gretchen Whitmer (D) consistently stated she is not running for president, Mark Leibovich writes:

“Clearly, though, Whitmer was happy to go through the Kabuki of being interrogated over whether she might change her mind. She didn’t bother with the annoyance that many ambitious pols feel compelled to feign—it’s such a hassle—when asked whether they might give the ol’ presidency a look. She giggled at many of my questions. Whitmer seems to genuinely enjoy being a politician, even the ridiculous and absurd parts of it, such as this.”
