Republicans step up effort to change Nebraska voting rules to help Trump

Key figures seek to bring about winner-takes-all allocation that would give Trump all five electoral college votes

Congressional Republicans are demanding an 11th-hour change to Nebraska's presidential voting system in a move that could transform the electoral calculus and tip the race to Donald Trump in the event of a photo finish.

With polls showing Trump neck-and-neck with Kamala Harris both nationally and in battleground states, senior GOP congressional figures are pressing the Nebraska legislature to replace a system that splits the allocation of its electoral college votes with the straightforward winner-takes-all distribution that operates in most US states.
