Anyone governing the USA needs to take into account the fractured nature of the major parties. They are more like coalitions now than they have been in the past. To pass legislation in such circumstances, rather than make it into one big bill, break it out into many smaller bills and get a different consensus on each.
As they stand, the Republicans are not able to govern on their own, due to the internal breach in the party. They must find ways to include Democrats on each vote, or they risk filibusters in the Senate, or a broken House Republican Caucus that can’t send anything up to the Senate.
