it. that could be one reason they're moving over. the other is that partisans, reliable republican voters, who have not been as fully with donald trump through the campaign as democrats have been with hillary clinton, well, some of those republicans have started to come back home. started to say that they now will vote for donald trump. vement.behind some of his but as we head into tuesday night, the key thing to watch is, both of these states are critical to donald trump's path. he need ohio. he need florida. hillary clinton cawi the map would still favor her in that regard. but, watch on tuesday if she can hang on to places like virginia. like pennsylvania. if she can hold both of those, she doesn't need a lot more to still get the electoral votes she will need to get elected. >> anthony salvanto. thank you. anthony and the rest of the campaign 2016 team will be here tuesday night with full coverage of election results. it all begins when the first polls close at 7:00 p.m. eastern

one of trump's signature issues. even before the election, it has led to a battle of word between trump and the mexican president. who invited the republican nominee to visit back in august. but the deep dislike of trump here in mexico goes back to the very beginning of his campaign, when he labeled some mexican immigrants as criminals and rapists. that led to protests here including the beading of trump pinatas and unflattering political cartoons that are in the newspapers almost daily. all of that makes hillary clinton the heavily favored candidate south of the border if only by default. elaine, the general feeling here is that donald trump has the made this election personal for the people of mexico. with much at stake for both countries. manuel bojorquez, manuel, thank you. a man arrested by the white house saturday wearing a mask and carrying a gun. the man was confronted by secret
