Some Senate Republicans on Tuesday mulled the idea of writing a budget that would allow them to pursue tax changes that lost significant revenue, weighing the possibility of a $1.5 trillion net tax cut over 10 years.

That approach would allow them to bypass the filibuster through budget reconciliation, the legislative procedure that allows bills to clear the Senate with only 51 votes.

But because of rules preventing reconciliation from adding to long-term deficits, the strategy likely would require that at least some tax provisions would have to be temporary.

House Republicans have staked out a different route.
