You look like jubilating, hahahaaa. But I agree with you that Mr. Trump knows what he is doing - questioning McCain's war heroism and the slur on the Mexicans. There are always 2 sides of the coin. Mexicans would hate Mr. Trump but how many Mexican voters in the US would not vote for Mr. Trump and how many would? Despite that racist statement, I'm sure there are Mexican voters who would still vote for him, i.e. if they believe in his platform.
There are an estimate of 1 million Latino voters that come of age (18) in the USA every year. Mexicans are Latinos. All Latinos do not like what he said. He has screwed himself and the republican party be making those statements.
Think of it as this way. I'm guessing your tribe is Tagalog (Luzon). If trump called all Bisaya rapist, would you get offended? If I called all Iliocanos murders, would you get offended by that? Maybe not directly but the finger was pointed at Filipinos. So yes, Latinos got offended.
