May won't even get the 'deal' she's hoping for after the Chequers week-end. For a start they have no solution to the Irish border problem. Even if a watered down deal is achieved with the EU (as any deal IS better than no deal), it will be voted on in parliament and likely to be rejected. This would probably mean a GE. Given the time scale of that, they would have to ask for an extension to Art.50. If Labour offer another vote on the EU options, they might well win an election, in spite of Corbyn. If there's another vote I would think it will be to stay in EU though a lot of damage has already been done to the country, and I don't underestimate the popularity of those shysters Farage, Johnson & Mogg. The result might be close again.
