Killer Mike's got an interesting take on second chances -- ya might never get one with the love of your life, but there's always Bernie Sanders in 2020.

We got Mike leaving J Prince's book launch at Tree Sound Studios in Atlanta and got his thoughts on the 2020 election -- specifically will his guy Bernie run again, and face off against President Trump?

Didn't take long for him to flash a wide grin. Make no mistake, Killer Mike still has his eyes on one particular prize -- and adds, another Bernie run is what's best for the country.
