Do Democrats Truly Support Hispanics?

Only if they are fellow leftwing robots spouting the 'progressive' bromides like ....diversity.....climate change....economic stimulus... etc. If they hold conservative/libertarian values, then they are persona non grata. An example is Miguel Estrada, whose appointment by Bush II to the DC Circuit Court of Appeals was blocked by Democrats. Some staff strategy memos for Democrat Senator Dick Durbin were revealed by the Wall Street Journal in 2003 (italics mine):

November 6, 2001/To: Senator Dick Durbin
"You are scheduled to meet with leaders of several civil rights organizations to discuss their serious concerns with the judicial nomination process. The leaders will likely include: Ralph Neas (People For the American Way), Kate Michelman (NARAL), Nan Aron (Alliance for Justice), Wade Henderson (Leadership Conference on Civil Rights), Leslie Proll (NAACP Legal Defense & Education Fund), Nancy Zirkin (American Association of University Women), Marcia Greenberger (National Women's Law Center), and Judy Lichtman (National Partnership). . . .
". . . The primary focus will be on identifying the most controversial and/or vulnerable judicial nominees. The groups would like to postpone action on these nominees until next year, when (presumably) the public will be more tolerant of partisan dissent."

November 7, 2001/To: Senator Durbin
"The groups singled out three--Jeffrey Sutton (6th Circuit); Priscilla Owen (5th Circuit); and Caroline [sic] Kuhl (9th Circuit)--as a potential nominee for a contentious hearing early next year, with a [sic] eye to voting him or her down in Committee. They also identified Miguel Estrada (D.C. Circuit) as especially dangerous, because he has a minimal paper trail, he is Latino, and the White House seems to be grooming him for a Supreme Court appointment. They want to hold Estrada off as long as possible."
