Run the mega-poll's own vote shares through our model and Labour still gets 358 seats. The difference from our 316 is a weaker Conservative Party and a stronger Restore Britain, not the tactical voting the coverage focused on.

Four days out, our forecast gives the Democrats a 65% chance of the Senate, up from 43% on Monday, and 83% for the House. A polling miss like 2014, 2016, 2020 or 2024 would still keep the Senate Republican.
