The key demographics the left have counted on, Blacks and Mexicans, are increasing in their support of Trump.
There should be many from various groups: Blacks, Latinos, Jews, Women, Unions, plus all of the the people who now have jobs, or better jobs, or higher paycheques, etc. All have a reason to jump on the Trump Train. If he can peel off enough from each of these groups, plus his base, the people voting “I HATE TRUMP” shouldn’t have a chance.
