HR Clinton is running, has been for one solid year. And Kamala Harris will not measure up to HRC's ankle, and her billions that she is sitting on. Why the entire field of opponents will not be able to raise combined what she has in her war chest right now.
HRC has a solid base of 35-40% within the Democommie Party. No one but Bernie can come close, not Kamala with her nasty disposition, not Booker the gladiator, not Uncle Joe, the perv, not horse face Kerry, simply stated no one will come close. Bernie will get far smaller numbers because in 2016, he was the never Clinton candidate. 2020 will divide that vote between 12-20 folks. And Schultz and Bloomberg, all their money will result in the same performance as Jeb Bush in 2016...rooms of money to get 1%.
So, she is running, and she will run away with the nomination. She will win enough primaries early on to make it impossible when the rest of the pack is thinned out to catch up.
In the general, all she needs as a strategy is to live in PA, OH, WI, MI and FL, and depending on the economy, she stands a solid chance of winning. Don't let the jack*sses like Durbin fool you, she is still a power to be reckoned with.
It will be TRUMP vs CLINTON in 2020
