The constitution allows foreign born presidents; what it doesn't allow is presidents which are not citizens by birth. (Ted Cruz is foreign born. John McCain, born on a US base in the US controlled Panama Canal Zone, is a marginal case. Both have been accepted as being eligible to be elected to the presidency.)

Ted Cruz is also a Latino. So in principle the situation in the book could be obtained by having Ted Cruz succeeding Donald Trump (or Bernie Saunders) in 2025, and being reelected in 2028, or succeeding Bernie Saunders (or Mike Pence) in 2029. James' review, which doesn't mention the president's politcal alignment, is compatible with Shriver calling out Republican financial profligacy.
