By who's measure?
Approval measures, like survey polls, are dependent on questions asked and who is asked, as well as who does the asking. Who do you trust that understands both the political and cultural nuances with a district composed so diversely, yet predominantly Hispanic? And the Hispanics certainly not homogenized.
Her problems in her home district are all self created. It is a district with many small business owners of ethnic family businesses. Young extended families are predominant, not millennials. Illegal immigrants are not welcome by those who played it straight. Small personal and violent crimes are a great issue. She ignores the everyday issues that concern the constituency. She ignores the elderly. She ignores the drives for more libraries, education improvement, security, local sports, and speaks of protecting prostitutes and pimps, a plague in the communities. Her lack of availability in the face of national headlines which her constituency is disconnected works against her.
She presents an image of elitist upperclass educated with a constituency that is mostly blue collar, minimally educated but not ignorant. Her concerns are not theirs. She has not entered the local social groups, distanced herself from the churches in a highly religious district. Millennials of the left may love her rhetoric, but she neglects than many of her constituency escaped leftist countries in disarray, at times fleeing for their lives. She has no contact with the growing Asian minorities.
One of my former Venezuelan neighbors calls her "little Fidel." That isn't a compliment. There are many who see her as dangerous as Che. These are people who haven't voted in the past, but they will this next election. You tell me how aware the media is of these potential voters. How aware of them are you?
These are not pro-Trump people, or even pro-right, the latter which they detest as much as the left. They are people who want the American dream for their children, whatever that dream means to them. She has not provided the answers to their questions or solutions for their problems.
BTW, if you believe her version of feminism is welcome by the women of this constituency you would be dead wrong. They do not welcome trans gender rights, gay rights, victimless drug crimes, even tho many participate in such "sinful" behavior. The hypocrisy is theirs also, but the don't want to hear about it from those who want their respect. For these women, the family and church come first. They still love Evita. They despise Castro's mistresses.
