Yes, she will take Julian Castro in an attempt to lock down FL, PA and NV, CO senate, as well as win IL, WI. She wins around 300 electors against Jeb or Walker and leaves GOP with a comfortable margin in House around 233 members.
PA wont care one bit about Julian Castro. PA is an old white state. FL is mostly Cuban and Central American with few Mexicans.
This is something people who think Rubio or Castro would appeal to a broad range of hispanics forget. The group is not united. Mexicans are not likely to support Rubio and Cubans and lesser extent PRs and DRs wouldnt support a Mexican.
Castro would help in AZ, I am surprised you left that one off but included the old white people state of PA.
