I don't put credence in the assertion of one poll that Clinton only has 51% of the Hispanic vote. This poll is probably closer to reality for Hispanic voters although it may be low on Trump's support.
Castro is a real lightweight. Mayor of San Antonio - big deal. Then an affirmative action pick as HUD Secretary. Whoop-De-Doo. A real pandering pick and will be seen as so.
Can’t compare to Pence, experience wise.
We’ll see. Pew Research also found Hillary underperforming among Hispanics (58% vs. Obama’s 70%). The theory is that the Hispanic macho culture prevents many of them from voting for a woman. She also did poorly with Hispanics during the primaries.
