The $640 billion McCain topline, which does not include funding for overseas operations, would represent a huge increase over previous budgets. It's $90 billion more than the fiscal 2017 budget, $54 billion more than what President Obama requested for fiscal 2018 in last year's budget and $7 billion more than the last pre-sequestration budget produced under Defense Secretary Robert Gates predicted for fiscal 2018, according to Katherine Blakeley, a research fellow at the Center for Strategic and Budgetary Assessments.
