Trump has been so successful that they really don’t have much to choose from.
Economy? Jobs? Security? Terrorism? War? Wages? All better under Trump.
Thus, the Dems have been focusing only on “get Trump”.
In the meantime, this idiot Cortez comes along with a message of communism and a large base of young, foolish, and ill-informed voters ( ironically, a situation that the Left itself encouraged by manipulation of the media and school curriculum), and she puts out an actual plan - horrifically stupid and untenable, but the only plan.
Now, the Left has its starting point as it seeks to define it’s planks for the ‘20 election.
There are a lot of hard lefties on this very board who will vote 3rd Party in the ‘20 election unless their hatred of Trump personally exceeds there desire to continue to live free in the US (they have already let their hatred of Trump outweigh what is best for the country in trying to get him unseated with lies and duplicity, but now they will have to let it exceed their own personal interests, and I don’t think libs will go that far).
